Top Ten Chiller-Thriller and Crime Korean Dramas

Many people in general think K-dramas are all about romance and nothing more. We all know how potential Korean romance is, and getting dizzy over feels is a common criteria for all K-drama lovers. However, there are these dramas that scoop out your soul while you're watching them, and let me remind you that these chills don't always revolve around only romance.
The Top Ten
1 Signal

Yeah I agree Signal is really good. When I was completely new to Korean drama, I decided to search up on Google "top ten Korean dramas" it's was around fourth or fifth some lists but the reviews were nothing but praise. The main concept is that two detectives one from the past and one from the present both work together in order to solve cases which may relate to themselves or their peers. Then I watched it...the reviews were spot on. If you've watched episode 1 then it's extremely hard to say you didn't enjoy it. The acting one of the best I've seen not in just Korean drama but in T.V. itself. When I watched Signal, it definitely piqued my interest into Korean drama and movies.

I will wholeheartedly agree. This drama, I don't even have words for it. It kept me on my toes till the last end, and then...poof, I was literally left breathless, as if though I had ran a marathon. You can feel every single thing the actors are feeling. They laugh, you laugh. They cry, you bawl out. Each cases they solve, will keep you up, as if though you're in the drama and solving the case alongside them. This drama had been on my recommendation list for some time, and like many people, I was obsessing over it "to watch, or not to watch" I went EVERYWHERE looking for reviews regarding this show. But I still didn't watch it (lol) Finally, when I was out of "my type" of dramas, and the review here was my pushing edge. Then I gave it a try. Let me tell you this, I was beating myself over with the fact that I hadnt watched it earlier. Speaking of which, I think I'll have my Signal Marathon for the second time. Toodles!

Signal. I will tell you why this is number one.
First of all, no movie will ever be amazing if you feel like the acting was forced. Because in signal, through all the episodes, not once did I feel like it was forced. It was so natural. When they cried, you literally will cry too because it feels too real. The actors impressed me deeply and I think I haven't seen a drama whose cast was this incredible.
Second of all, the story line. This story will leave you speechless. Seriously. The story deals with 5 VERY important cases to the story line. Each case, I promise you, each case will leave you shook. This drama is filled with suspense where you're literally shaking, waiting for the next moment to occur because you have no idea what will happen. It will leave you crying because it perfectly displays human cruelty. and it will leave you laughing because damn, the script writer is too intelligent.
The shooting and producing is very very advanced. The director and producers did an ...more

This drama is hands down the most amazing one I swear. I just hoped they would remake this into a movie but anyhow its gorgeous and very well arranged leaving me speechless all the time. If you love romance drama then this isn't the one I tell you. This drama is damn lacking in romance but I seriously don't mind because the thrilling genre itself makes you forget about kissing scene for a while. I did get very attached to this drama and almost cried when it was about to end. But honestly can't get over it and totally impatient for season 2 in 2018

2 Gap-Dong

Even though it's a common police-procedural drama that messes with your psychology, it is so much more than that once you advance through the episodes. There were moments when I literally shook. There were also moments I shut down my computer and couldn't watch an episode till I had recovered. Lee Joon, being an idol actor, took absolute control and amazed a lot of drama fans, moreover, shocked them. An absolutely amazing drama. And let's not talk about the killer OST that just triggers your feels.

I'm watching it now and it keeps me questioning who is Gap Dong? I've been directed into this site because I'm looking for answers but I don't wanna spoil myself. I have to refrain from looking for answers and watch it myself till the end. I bet this is really the best crime thriller drama. I'll get back on you when I already finished watching it and have all the answers. Every episode will keep you alive.

Agreed all three were great shows

This is my #1, 2nd tunnel, then Voice

3 Tunnel

The best thriller ever. One of Ji Sung best drama! The story line is really intense, no time to catch a breath! Definitely a must watch

Seriously, such a plot they have there... I'm amazed by the actors, background ost, the twists, the trust, love, stories... They're all perfect together, I'm in love. Best korean drama I've ever witnessed, it taught me a lot and still teach me. thank you Tunnel family from the bottom of my heart.

After Signal and Voice, I continue with Tunnel and it turns out GREAT. PERFECT. If I could mention my top 5 crime-drama that would be : Tunnel, Signal, Voice, I Hear Your Voice, and War Of The Sun. All of them will never bore you.

Just gotta say one of the best, great suspense, I just It absolutely, writer just great imagination, please keep them coming, gap dong, signal, voice love them all, Viki is my favorite place to watch Korean dramas You guys

4 City Hunter

Okay, first of all I'll be honest--getting a grip of this from the first episode was hard for me. It involves marines, political conspiracy and lots of grudges. A surviving soldier and a stolen child that he raised as a weapon of revenge combined is not your average mac and cheese. This series drained me when I watched it, made me lose my breath a couple of times, was fun, was fresh, and was oh-so-thrilling at times. And as an addition, it's not everyday you see Lee Min Ho being your under-cover vigilante slash revenge-seeker on screen. A beautiful watch.

This amazing drama is more than just vengeance. One of the few dramas that are worth-rewatching!

This drama is crazily awesome and really cept me at the edge of my seat when I was watching it

The Best Korean Drama of all time

5 Voice

The voice drama is so good! Make your adrenaline so much rushing. Both crime and general story makes everybody guessing and confuse who is the killer! Hope for the next season

The entire series kept me on the edge of my seat! Right from the first episode. If you love criminology & psychology, this show is definitely for you. :)

Loved this thriller from the very first episode, There was a lot of suspense and mystery and had me on the edge of my seat the whole way. Excellent acting all the way around. I didn't care for the last episode, I feel it was creepy and weird and didn't end the way I would have liked, but perhaps it was fitting for this drama. I could not stop watching, wanting to know what happened next, it just sucked me in! Great drama!

I loved a story about proving something that the others tell you can't do or it can't be. This drama makes me cringe of how bad/insane the killers way to kill the victims, but if the killer is great, the detective will always be more great! I can't describe more about how good the drama is, it is about 3-4 months ago so it difficults to remember the detail... all that I know after watched the drama, it always be my standart to search another crime kdrama! I hope u guys watch it!

6 Nine: Nine Times Travel

Another TvN drama that I couldn't resist putting up. It might not be under the thriller genre, but it will thrill you, no doubt. When you add a famous news reporter who's dying and a few incense sticks that help him travel back in time, there will be drama. A man sets out to make amends to his life through this unnatural time travel method.However, the changes are devastating, and once you proceed through the episodes, you realize there's a lot of crime involved. I wouldn't really call it an exact crime drama, but it gave me chills, and probably is one of the bests out there, in fact.

This was a fantastic time travel drama done right. I had nothing else to watch and decided to just go for it and I was so glad I did. I didn't sleep for day marathoning this. a must watch!

I love this drama to bits!

Best travel time drama

7 Defendant

Wow it's so good, I am amazed. Such a great and unique storyline. It will keep you from taking deep breaths and will wrench your heart at the same time. Just great!

This actually should be first! The whole plot is great! I needed paper to crumple throughout watching this cause you would greet your teeth by the tense that's happening. I love this!

Highly recommended.. Has to be the most loved drama 2017 ji sung proved to be still the number one actor in my lists. Great performance from all the other casts but the lead was electrifying

I love the whole story line and how each of the characters have their own conflicts and stories! It's definitely one of my favourite Dramas so far

8 I Remember You

This drama is something I would recommend to people who are new to Korean dramas or existing fans. It is also family driven, focused on a father, and two brothers. The plot and performance was tip top. I did not expect much, however it blew my mind away with the twists and turns. The story runs smoothly and it was not confusing despite the amount of information needed to make sense of the story. Although romance was not a focal point, the tiny bit of it will make you fall in love with the love between the two leads. All in all, it is a drama to watch if you are a fan of police procedural genres, and a fan of crime dramas.

I admit that I am fairly new to kdramas but this one just really stood out. It's been days since I have finished watching the series and yet the story's constantly been in my mind until now. The plot is so good! It got me hooked on every episode. The actors were also amazing, everything was flawless! I didn't mind the lack of focus on the romantic relationship of the two leads at all. Kudos to the writer and the team behind this drama. Much information about psychology and police procedures was included but as one who is not familiar with any, has understood and even got interested to it. I'm having trouble searching for other kdramas now that would match up to this drama. I simply cannot move on from the impact this drama's caused me. A definite must watch!

I only saw this drama for SIG...but it captivated me till the end. Especially the the way they portrayed the characters. It was so easy to relate to the characters...even the antagonists...It really is a beautiful masterpiece...despite its flaws. I loved how they used pretty faces as antagonists which symbolizes that looks are deceiving. This and The devil are so similar yet so different at the same time. Both the dramas make us empathise with the killers. But the question they make us ask are different. IRY was definitely worth the watch.

Before I watched this drama, I was in a kdrama stump. that's when I stumbled upon I remember you and honestly I don't think I've ever made a better decision. the storyline is so interesting and the cast is AMAZING at portraying the emotions. the ratings really didn't do it justice. I started watching this on a Saturday night and finished it by Monday. I would and probably will recommend this drama to everyone. WATCH IT

9 I Hear Your Voice

I could easily put most of Lee Jong-Suk's dramas in my list because I am so biased by him. But this drama stood out to me. A combination of a dreadful incidence, promises, crime and fright all gathered into a courtroom drama is what I needed in my life. Did I mention the ability to read minds? He hears everyone's voice, from the depth of their souls. He even hears the minds of his most hated and most loved people. I love this drama so much, I don't even know where to put it in my list, so I'm just leaving it here.

It's one of the best dramas I've ever watched.. There's enough romance, thriller etc all at the same time. Lee Jong Suk as usual is perfect. He was excellent.

This is my favorite Kdrama! I Hear Your Voice is such a solid drama. The leads have great chemistry.

It's simplely amazing you can never get bored of the major plot twists

10 The Devil

This is a classic.Not really. A 2007 drama revolving a tarot-card reader who also has some specific psychic abilities, a mysterious lawyer and a detective with regrets of his own. As usual, all these fine people are interconnected through a past occurrence. I loved this drama, and I loved watching it, I loved the chills it gave me and I loved the tears I shed for it. My love for this plot and drama would probably explain why it still exists in my list after eight years.

I had very few expectations when I started this. But the drama really did surprise me. I don't think I have ever felt as much sympathy for the bad guy than in this. The drama questions the very nature of being bad. Who is the devil? Is the good guy really good? Is the bad guy really bad? These questions filled up my head as I watched this.

The Contenders
11 Two Weeks

Another amazing plot that I haven't seen fully. Shmuck, what am I doing with my life? But according to thrill lovers, this one is a must-watch with its plot revolving around a man who has been accused of murder and has to save his dying daughter before it's too late. I can only imagine the amount of times I'd have to shut my computer down for this.

Yeah.. what an amazing plot! I'm grateful to all of two weeks' team for giving me a chance to watch a drama that's amazing..

This is a must watch! I watched all episodes in one go from 10am till 3am non-stop.

Wonderfully intense...with some sweet moments!

12 Healer

Everything is so good in this...
It's complete package for people who want thriller and crime with a love story...
Specially you'll love the main leads character...he is awesome

The Best Drama Ever (or Best Thrilling Drama ever), It's a mix of feelings with a great mystery and superb acting and many unexpected moments
Supporting actors has their focus in the drama and are important as the main actors to the story,
Action-Romance-Thriller in the best way possible.

The ending is such a surprise you wouldn't ever have expected.

Just watch it without doubting its greatness (It's a masterpiece in almost every way).
you have to bear with the first half of first episode as it's a little confusing at the very beginning of the show.

the OST is just fantastic, chilling and beautiful English vocals, you will be brought back to the drama even after years when listening to these amazing soundtracks.

there is not a dull moment in the series and you might want to marathon it in a few days, so free-up some time before deciding to watch it.

This is by far the best thriller drama I have ever seen which has the twist of plot woven so well and Ji Chang Wook in all his charms. The cast lived up to the expectations of a thriller drama lover. This definitely makes you fall in love with the actors, making you watch it again.

Best 1. Plot with amazing story telling style, unique characters with perfect casting, super duper ost, acting are just spot on. A new era classic of all time. Action, comedy, romance, relationship what not!

13 Wanted

One of the best korean thriller drama. Can't wait for the next episode! Love the plot.

Currently my Favourite drama now! can't wait for the next episode

Most thrilling Series I have seen Ever

14 I Miss You

Don't you just hate those dramas that drive you insane with feels and unbearable scenes from the very first episode? No,man, you gotta love em. You gotta, at least, love I Miss You. A tragedy of two children where the boy abandons the girls and leaves her for dead in the hands of kidnappers is no mild. You need a lot of strength to watch this drama, I know I did. Heart-wrenching crime at first, and soon it's packed with thrills when the boy becomes a dedicated detective for the sake of his past mistake and swears to find the friend he abandoned. When Yoon Seung-ho is antagonizing JYJ's Mickey as the lead, you need no other reason to watch this.

One of the most deep and thrilling kdramas I've ever watched. After watching this, other series seemed to lack depth. Definitely recommended!

Love this too

15 The Village: Achiara's Secret

I don't know where to start about this kdrama. It's definitely not explicit because each episode just leaves me questioning more and more, in a good way. It's absolutely suspenseful and contains enough gore scenes for me to continue eating while watching. I was deep in this drama for all 16 episodes! Suspenseful music, YES! Twist, YES! Mystery, DEFINITELY! Thriller, OF COURSE! Great actors/actresses, POSITIVELY! Achiara's Secret has left me yearning more.

This drama is highly recommended for you guys! I just love everything about this drama!

I love this drama! One of my all time favorite.

It is sooo amazing the plot is so mysterious you ll be shocked in the end ;the actors are so good you get action crime detective thriller mystery and supernatural and horror like it has everything not to mention that moon ga yong and sung jae from btob are leads

16 Golden Cross

I still haven't seen this and basically am referring to the thoughts and ratings of fans, trailers and the general plot. A prosecutor gets entangled in messy business with the most influential people in Korea. He has to go against this certain circle of people to clear off his father's name who has been accused for the murder of his sister. By the sounds of it, it's going to be extremely awesome, and I want to watch it asap, and maybe it will go way up my list after I do.

17 Bad Guys

man this drama was just awesome.. I would really recommend watching this is your new to kdramas... all the actors gave their best performances and the script was also great... it showed the true nature of the human mind.. I kind of began to feel sorry for psychopaths after this( maybe because the actor was too good)...

Criminals solving cases whilst learning along the way, what it truly means to be human and the difference between a man and beast.
But that isn't all because somehow, these criminals and the squad leader "Mad Dog" are linked, and it's only a matter of time before the truth is unraveled...
Though not before a series of misunderstandings occurs and chaos ensues.

Loved the drama. The more I watched, the more enthralled I became. You know the acting is good when you feel sympathy and hatred for characters of a fictional world.

To combat rising violent crimes, the Police Chief asks Detective Oh Goo-Tak (Kim Sang-Joong) to form a team consisting of criminals. Detective Oh Goo-Tak is currently suspended from the police force for using excessive force. Detective Oh Goo-Tak gathers team members: Park Woong-Cheol (Ma Dong-Seok) who is a gangster, Lee Jung-Moon (Park Hae-Jin) who is the youngest serial killer with extraordinary intelligence and Jung Tae-so (Jo Dong-Hyuk) who is a contract killer. Also, Police Inspector Yoo Mi-Young (Gang Ye-Won) joins the team.

I like this movie so much because actors are very handsome and greatful. Then crime is the best

18 Partners for Justice

I was hooked from the first episode. I love this drama series. It just blew my mind. When u thought u know the answer, but reality are different. I love the main character Dr Baem Boek. Wishing that they will continue for the 3rd season and please bring back Lieutenant Cha!

All crimes and there is many autopsy scenes. through this drama you will literally learn so many new things and the different deaths in the drama are all different so you definitely wont get bored. let me just say the second season is much more interesting and there will also be this new character that is honestly very hot in the drama like woah and his voice is sooo nice. its just the guys background story is also very interesting. I wont spoil but this drama is definitely worth the watch because I honestly prefer romance over anything but this caught my eye and I wasnt bored through the entire drama and I managed to finish it in a few days even though there was 32 episodes in total for 2 seasons. I hope a season 3 will come out soon because I can't wait!

Just loved this drama. Mostly in other dramas and movies they don't follow the normal procedure of investigating a crime but in this they properly show the procedure not only that in most dramas they only show from the detective/prosecutor view but in this drama they show the scientific view of science. Also the cast, they're so good. Everything about this drama is just so proper and is done in a scientific way not like the fantasy kind of, it also has many humorous scenes to not make it boring. They ended the last episode on a cliff hanger and the 2nd season is going to come soon and I'm eagerly waiting for it. If you're fed up of the normal fantasy kind of dramas and want a reality based mystery action thriller then this is a must watch.

The BEST drama detective drama I've watched so far. You'll surely get hooked from the first Episode up to the last. Both seasons one and two are thrilling and would really keep you tensed. Actors and actresses were able to portray great characters that made the drama a success. No Min Woo's acting on the second season was really impressive because he was able to make his character stand out even though he was one of the antagonists. This drama is HIGHLY RECOMMENDED.

19 Stranger

Amazing drama. I didn't dislike a single thing, and that's a lot to say because I'm really picky. I even liked Stranger more than Signal. From the first to the last episode it never gets boring, everything develops at the perfect pace.

Great characters, plot and actors (literally not a single bad actor in this drama). It has a psychological aspect, wich I love and the two female leads are kickass, not the useless idiots of most k-dramas.

I believe Stranger should be on the top of this list.

One of the few kdramas I stayed up until I finished. Since I'm very picky, this one is really good. I used to skip scenes, but not this drama.

One of the best suspense-crime korean dramas I ever watched. Everyone plays their role and characters very well, especially the lead actor, Cho Seung Woo, play role as Hwang Shi Mok, a high integrity prosecutor which can't feel any emotion. The plot and story line are great also. I really recommend this drama. ^^

Worth the watch. Hoping for season 2 though. I would say, the first few and the last few episodes are so good.

20 Doctor Stranger

Its quite a heavy drama but definitely a must watch.

It took an emotional toll and it’s very heavy however the story is incredible and kept me interested until the ending credits.

21 Heartless City

Just one of the best dramas in the Crime Noir theme! It's really profound with great plot twist and wonderful actors! Puts you on the edge of your seat in every episodes!

Amazing drama. My favorite character in this was Jung Shi-Hyun.

Awesome! The acting is superb!

The best! Jung kyung ho was amazing! out of this world amazinggg! Must watch!

22 Remember: War of the Sun

I recommended this k-drama are heavy scene that about law,don't expect love scene because this is reality what we have now in this society and the government, this is my favorite so far this k-drama that you will learn about the law and being fair to people accused and using people that involve money.

I love this drama so much! the story Itself is just amazing and with these great actors just perfect! I can just recommend it!

This k-drama definitely intense the scene, should watch this drama that about the law and victim

A must watch kdrama! Awesome plot, once you start the first episode.. u can't stop to continue and continue the next episodes! Really DAEBAK!

23 The K2

Loved it. Seen it thrice already! it's a good watch. good twists. Great acting by the lad actor. Amazing action. Even the bad guys look dapper!

This show is an intensity pill and it’s just so good that you can’t stop watching. Highly recommend especially the action scenes mixed with the OST. Props to all the actors and actresses. They did an amazing job.

24 White Christmas

I just finished watching this drama and I have no words to describe how brilliantly the storyline has been crafted. Every episode makes one more curious about what could happen next. It's very unpredictable and unique. All the actors did justice to their roles. A must watch for all thrill lovers.

Amazing! White Christmas was brilliantly written. It has a lot going. Dark mistery, thriller, rites of passage and much more. As it has plot twists and a good story, it also depicts the whole incident with a beautiful perspective of humanity. Cannot recommend enough!

Its one of those dramas which really gets your mind working. Mystery thriller drama with amazing actors, and plot twists. When you start watching, make sure to watch until the end.

A short mystery thriller, where the plot is full of mind games! Really puts you on the edge of your seat in certain episodes... A must watch for thriller mystery lovers..!

25 God's Gift: 14 Days

One of my favorite drama.. The last episode really makes me speechless..
This drama is about a mom which lost her daughter and have a chance to travel back to 2 weeks before her daughter die. With a private detective which also travel back to time, she do everything she can to find out who will kidnap her daughter and why that happen..
After watch 2 episodes, I didn't put high expectation on this drama and almost decide to not watch the remaining episodes.. however, the suspense is started from 3rd episode and I could not stop to watch it after that haha..
Really love how the actor and actress play their character and role..

This drama is listed below so much that I would miss it totally. This should have been placed with two weeks where u get hooked with the drama till the end. So much of suspense, twists, emotions. Totally loved it and lead actor. This is the first time I am watching him and he did his role perfectly. wow such a pity he had done only few dramas. Would like to see more of his works. Awesome drama. Glad I watched it.

VERY sad but SO good. Recommended to my friend who rarely watches kdramas but more korean movies because she has high expectations for thirller and she really like it too. sad but its GOOD.

Such a great drama with a great plot and very addicting. Few bits of teary moments
