Best Sci-fi TV Shows

The Top Ten

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.

Best series ever. Brilliant characters and amazing storytelling. As for those who think Doctor who is better just because it's Been around for over 50 years, that does not mean it's a great show. Let me tell you that having watched every episode of dr who including the stills, most seasons are pretty dull. The x files was brilliant throughout its entire series and had two excellent films whereas the Dr who movie was a flop.

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 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.

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.

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.

Doctor Who deserves the top spot, it's been running for almost 56 years and has a massive fan base. Heck, when it was axed for a short while fans wrote a song to try and get it back

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

Star Trek Star Trek is an American science-fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise.

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

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.

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

Incredible story lines and amazing original episodes. Episodes that have never even been attempted on a T.V. series

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.

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

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

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.

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

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

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.

The only sci-fi show I really like

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.

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

Such an amazing show.

The Contenders

Red vs Blue

An amazing thrill ride of sci-fi, drama, action, and most importantly, comedy. The characters are AMAZING. The plot can be ludicrous, but its charm and self-awareness always trump the ridiculousness of the truth for the show's benefit

It has stronger characters then most shows above.

Space: Above and Beyond
Power Rangers

Really?

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.

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

Stargate Atlantis

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

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

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.

This is the standard by which all other shows are measured. Great character development, intelligent plots and a very loose timeline. There is no one else I would want to take me into battle over Captain Picard.

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.

Better than the Original, that's for sure.

Terra Nova
The 4400

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

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!

The best good job miilmac

Buck Rogers in the 25th Century
The Outer Limits
Quantum Leap

Ithank the qantum leap s very good show

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

YES! This show is SO underrated

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