The Top Ten

1 The X-Files The X-Files The X-Files is an American science fiction drama television series created by Chris Carter. The original television series aired from September 10, 1993, to May 19, 2002, on Fox.

Doctor Who is the best Sci-Fi T.V. show, it ran for more than 50 years and it's still running and it's still good, it's the last good T.V. show ever to exist and it has the biggest fanbase of any T.V. show ever to be made, The X-Files is not as good as a matter of fact and ran way shorter, yet it isn't as popular or heart warming.

The X Files forever! It's the most amazing show ever! And Mulder and Scully - best romantic couple!

TXF is the first sci-fi show with movies - and both of them are something really surprising - you have to have a head on your shoulders to understand them!

The X-Files is the best show ever! Kim Manners started on this show, and then Supernatural. Then it inspired a Supernatural episode. This show has open the barriers for shows of this nature and is still mentioned or copied off of. And not just Sci-Fi things either... - 2shy

Not the best, but one of the best, The best sci-fi show ever made is Doctor Who, which ran for more than 50 years, beating The X-Files. - nelsonerica

The X-Files is not the best, that would be Doctor Who, Doctor Who has the best plot, and it's been running for more than 50 years, it's the longest running sci-fi T.V. show, and nothing will ever replace it, The X-Files is just a second place sci-fi show.

I so agree with those who say Doctor Who is the best, It's completely true, Doctor Who has excellent writing, amazing acting, good plots, detailed storylines, awesome adventures and the biggest fanbase of any sci-fi series, yet it's the longest running, more than 50 years, yet they hardly even ran out of ideas.

The X-Files wasn't as good and didn't have as much exciting adventures like Doctor Who does, and it only ran from 1993 to 2002, nowhere near as long as Doctor Who, and it didn't have the strongest fan base. - nelsonerica

2 Doctor Who Doctor Who Doctor Who is a British science-fiction television programme produced by the BBC since 1963. The programme depicts the adventures of a Time Lord called "the Doctor", an extraterrestrial being from the planet Gallifrey. The Doctor explores the universe in a time-travelling space ship called the TARDIS. ...read more.

The writing, producing, directing, acting, editing, special effects, and everything else are amazing for every single episode. Best show on television!

David Tennant...

Best sci fi show ever... nothing will replace it when it's gone... I hope it'll last as long as the original

I love this show! However I thought David Tennant was better at playing the doctor than the current actor. I give this #1 for sure. After which comes Farscape. Both really good shows.

3 Star Trek Star Trek

It's Star Trek. It's THE mother of all other sci-fi series... And who can say he doesn't like their mother? Just go to any Star Trek convention and feel the cult around you. Resistance is futile!

The Star Trek pilot aired in 1964 so in fact it is only a year younger than Doctor Who. The original series is the benchmark for all shows that came after it.

Yes, Star Trek is old, but Doctor Who aired three years before it. Still an amazing show.

Star Trek number one? Make it so

4 Supernatural Supernatural This haunting series follows the thrilling yet terrifying journeys of Sam and Dean Winchester, two brothers who face an increasingly sinister landscape as they hunt monsters. After losing their mother to a supernatural force, the brothers were raised by their father as soldiers who track mysterious ...read more.

There's no sci. Fic. Show can ever compete with supernatural. It's the best and there's no doubt about that. JENSEN ACKLES IS SO TALENTED people try to notice that he's so great.

great storyline, acting, suspense, comedy, horror, very simple to understand and keeps getting better as each season goes by. - afex

The best sci-fic show ever! Jensen Ackles is incredibly talented and Supernatural wouldn't BE Supernatural without him.

Not sure how this exactly qualifies as sci-fi, but I love it anyways.

5 Battlestar Galactica Battlestar Galactica Battlestar Galactica is an American science fiction media franchise created by Glen A. Larson. The franchise began with the original television series in 1978 and was followed by a short-run sequel series, a line of book adaptations, original novels, comic books, a board game, and video games.

I prefer the original 1978 series.

The best sci fi show ever( obviously the latter day remake, not the original that was truely terrible)

An awesome show how it can be on no.6 it should be at in top 3.

Utterly fantastic the portrail of Adama is fantastic the writing is amazing the cast is out of this world a truly splendid show

6 Stargate SG-1

I would like to see more of stargate with the old actors init. dc

Definitely my favourite Sci fi franchise, loved SG1, just started watching it all again, Atlantis was better looking visually, both had great casts with a mix of humour and action they were and are great.

While I bought and watched "Stargate universe" it is the worst part of the franchise. They try to make a Battlestar galactica/Voyager clone, I only enjoyed a few episodes of the two seasons.

I watched every episode of this from start to finish in about a month. I couldn't stop. It would be 3 in the morning, id have to go to work a 7 and id still watch 1 more episode. I couldn't help myself. Call me sad, I call it dedication

Great characters teal'c for the win and O'neill is also awesome, good humor and plot lines in the later seasons there is also epic space battles.

7 Firefly Firefly Firefly is an American space Western drama television series which ran from 2002–2003, created by writer and director Joss Whedon, under his Mutant Enemy Productions label.

This is the best sci fi T.V. serial I have ever seen. Unfortunately it has been stopped after first season. It should be number one. People who have seen it definitely agree with me. So fan of the firefly vote for it.

This show changed my life - thexg

This show is definitely one of my all time favourites. Such great characters and stories, you can't help but fall in love with the show. Deserved much more than 14 episodes (and a movie).

Fourteen episodes? I am missing some. Great show

8 Babylon 5

This was an incredible series. The best aspects are the five year story arc, the writing, and the absolute lack of ridiculous 'relevant' plot arcs.

This was a complete, well-told story -- not a referendum on modern culture or recent history. Most Sci-Fi series rely on using political hot points to infuse their scripts with life, but this one was purely the child of J. Michael Straczynski's imagination, and it lives and breathes on the screen like nothing before or since.

This series has the deepest, most intricate story line of any sci-fi ever created. every episode ended with you wondering what would happen next and this show broke the barrier for ending with everything exactly the same as when the episode started. This show is truly phenomenal and deserves to be #1

If you're not voting for this show, then you haven't watched enough of it. Babylon 5's greatness lies not in the individual episodes, but in it's overall 5 year long tale. It's by far the best I've seen. I'd rate The Twilight Zone and the X-files high too, but Babylon 5 is pure SciFi fulfillment!

Just brilliant T.V. show - one of the greatest Sci-Fi creations ever. Not to mention superb visual effects for that time plus great story, acting... They don't make shows like this anymore. Too bad - Irina2932

9 The Twilight Zone The Twilight Zone The Twilight Zone is an American anthology television series created and presented by Rod Serling, which ran for five seasons on CBS from 1959 to 1964. Each episode presents a stand-alone story in which characters find themselves dealing with often disturbing or unusual events, an experience described ...read more.

This show was so diverse... It was so pertinent for its time and covered so many themes... Was dark, fun, suspenseful and loaded with surprise endings... My favorites were: To serve Man, Nightmare at 20,000 feet, On Thursday we Leave for Home, and Time Enough At Last...

The creator of the X-Files said that without The Twilight Zone, X-Files would never had been made. Both are worthy of the top seat. - mgenet

This show was, by far, the best sci-fi show...tied for second place - The Outer Limits and Star Trek...

Such an amazing show.

10 Farscape

Many excellent shows here, but I have to spread the Farscape love. It wouldn't have existed without Star Trek, but it was more fun, dark, ambitious and downright entertaining than any other sci-fi of its time.

One of the few shows to have real aliens (not just bumps on the heads), and a compelling story arc.

This show is cool, mostly looks like a drug fueld trip, but still great. - cheetahfur

The only sci-fi show I really like - nigelthewizard

The Contenders

11 Red vs Blue

It has stronger characters then most shows above.

12 Space: Above and Beyond
13 Power Rangers

Really?

14 Stargate Atlantis

best show ever, sci fi but doesn'ttake itself too seriously - FATRESS

Best sci fi ever... What amazes me is the role by Dr rodney mckay

Its Action Packed, funny and deserves to be in the top ten

15 Star Wars: Clone Wars

Best Show EVER. And that's coming from a High Schooler. Still pissed at Disney for canceling it. Then again, who isn't pissed at Disney?

Disney should've never bought out Star Wars. Then again, this is coming from an autistic girl who can't stand the Star Wars franchise. - PerfectImpulseX

Really good

Very good point Disney Ruined star wars T.V

16 Star Trek: The Next Generation Star Trek: The Next Generation Star Trek: The Next Generation is an American science fiction television series in the Star Trek franchise created by Gene Roddenberry that ran between 1987 and 1994. Roddenberry, Maurice Hurley, Rick Berman, and Michael Piller served as executive producers at different times throughout its production. ...read more.

How to sum up Star Trek in one word:

YEET

To people talking about how Star Trek is already on here, they're different T.V. Shows, it isn't like Doctor Who. It's like saying Star Wars A New Hope is the same movie as The Empire Strikes Back.
Well anyways, TNG is the peak of Star Trek. The original may be iconic, but TNG exceeds it, although both will have a special place in my heart.

This is just a Star Trek series and Star Trek is already on the list.

This is just part of the Star Trek series, which is already on the list.

17 Terra Nova
18 The 4400

Unique show! Should be #2 after The X-Files - Irina2932

19 Alf Alf ALF is an American science fiction sitcom that aired on NBC from September 22, 1986 to March 24, 1990. It was the first television series to be presented in Dolby Surround.

ALF is the best! Put this on number 1. it's my favourite sitcom!

21 The Outer Limits
22 Quantum Leap

Ithank the qantum leap s very good show

23 Futurama Futurama Futurama is an American animated science fiction sitcom created by Matt Groening for the Fox Broadcasting Company.

This show is cool; this is better than the Shimpsons.

Unless this doesn't go up any further, this list is bad and you should feel bad.

YES! This show is SO underrated - VADERtheIMPALER

24 Six Million Dollar Man
25 Sliders
26 Buffy

I'm obsessed with this show, everything about it is great! I love Sci-Fi but this takes it to a whole new level. Joss Whedon is a GOD!

The only Sci-Fi show that provided comedy, humour, horror, action, drama and everything else. - MutantGenesis

This is a perfect show but it is supernatural by the way not sci-fi but buffy should be at th etop of everything! The perfect show with a terrible ending.R.I. P buffy 1996-3003/R.I. P Angel 1999-2004/R.I. P Quality television.

27 The Prisoner

Short but very sweet series. Nothing like it before or since. Long live, Rover! - howie115

28 Torchwood

lOOOVE IT

29 Fringe

How on earth is Fringe this low. Was this list started today? A show that fans managed by force of will to keep on air for another season and half? This is unacceptable... Or the alternate universe.

Why the hell is Supernatural on the list, it's not even sci fi. Fringe deserves to be in the top 5.

Walter Bishop 'enough said!

32? What the heck are sea quest and sliders and how can they be ahead of Fringe. Heaven help us all.

30 RoboCop: The Series
31 Stargate Universe

Keep watching the reruns, can't get enough

The best Sci-Fi series of the past 2 decades. Universe was so much better than SG1 or other series. Pity it got cancelled over money and politics. SGU was the best (SG Atlantis 2nd best).

Science Fiction can't get any better. - Nebular65

Loved this show. Was haert broken at cancellation.

32 Knight Rider Knight Rider Knight Rider is an American television series created and produced by Glen A. Larson. The series was originally broadcast on NBC from 1982 to 1986.

33 Charmed Charmed

I LOVE EVERYTHING ABOUT CHARMED! It's such an interesting show to watch. I love all the characters, the special effects sounds stuck in my head, the perfect powers are so... Perfect and the plot is so interesting! No words to describe how much I love this show. My favorite character would probably be the oldest sister that passed away in Season 3, Prue. But I also love the other sisters. Every character has something special. And the show passes some great messages too.

34 Twin Peaks Twin Peaks Twin Peaks is an American mystery horror drama television series created by Mark Frost and David Lynch that premiered on April 8, 1990, on ABC.

Almost a worth-watching T.V. show... In the and it's not, though came close.

35 Mork and Mindy
36 Bionic Woman
37 Smallville Smallville Smallville is an American television series developed by writer-producers Alfred Gough and Miles Millar, based on the DC Comics character Superman created by Jerry Siegel and Joe Shuster.

Tom Welling is a really great actor. The best I've ever seen. Smallville is so amazing. It's the most awesome tv show ever. I love Smallville so much. It's way better than Vampire Diaries or Supernatural

Yeah it's Smallville, it's a great show, of course it's not what it use to be, but I still like it. I would also say ECW as well but I don't watch it so it's Smallville. - Undertaker15-0

38 The Expanse
39 Rick and Morty Rick and Morty Rick and Morty is an American adult animated science fiction sitcom created by Justin Roiland and Dan Harmon for Adult Swim.

Terrible show, one of the worst for sure

One of the best shows on T.V.

Best show of this era.probably!

This is the worst T.V. show ever.

40 Star Wars: The Clone Wars Star Wars: The Clone Wars Star Wars: The Clone Wars is an American 3D CGI animated television series created by George Lucas and produced by Lucasfilm Animation with the division Lucasfilm Animation Singapore, Lucasfilm and CGCG Inc.

If you want to put a sci fi show it should be a very cool one so this show is awesome.

41 Sea Quest DSV

Another place to Boldly go where on man has gone before

42 Lexx

Very interesting and creative Sci-Fi show with great visual effects. Farscape stole some ideas from this one but I love both series - Irina2932

By far the most underrated, creative, innovative and underseen sci-fi show ever. Pure fun and escapism. UNIQUE.

So underrated! So epic!

A great, innovative SF show.

43 Roswell

I love Roswell, even though the show was aimed at a younger audience. The deeper you go into the series, the more mature it gets. The plot of aliens hidden in plain sight, while not new, is treated with a fresh perspective.

44 Earth: Final Conflict
45 Dark Angel
46 ECW

ARGH, This x files #1 crap is getting annoying. ECW is way better. - Razor79

HELLO PEOPLE!!!

ECW! ECW! ECW! - anthony

47 Heroes

I Just started watching it but I know one thing, it should be at least on the top tens

48 Black Mirror Black Mirror Black Mirror is a British science fiction anthology television series created by Charlie Brooker, with Brooker and Annabel Jones serving as the programme showrunners.

It's fairly new, but think Twilight Zone and terrifying visions into the future, and you've got one of the most intelligent and scary shows in Britain right now.

49 Red Dwarf Red Dwarf Red Dwarf is a British science fiction comedy franchise which primarily consists of a television sitcom that aired on BBC Two between 1988 and 1999, and on Dave since 2009, gaining a cult following.

How is it only 50th this show is legendary

Fantastic sci-fi/comedy crossover. Anyshow that can make a come back after more than 10 years with the same cast has got to be a classic. "SMEG! "

50 The 100 The 100 The 100 is a fantasy-drama based live action show based of a book by Kass Morgan. The show was aired for the first time on March 19, 2014. In the show, we start three generations after a nuclear apocalypse.One large space station, made of twelve separate space stations, is suffering overpopulation. ...read more.

This show is a really unique take on a post-apocalyptic type of show and plus female main character! It deserves to at LEAST be in the top 15, not way down here in the 60s. Move this up!

(Star Trek should be in first, in my humble opinion; I would say Supernatural should be but it's not really science-y? )
