I know, I know. This is a hard one. Take all of the science-fiction shows ever, and determine a top ten? That's a really tough job, but a very entertaining one. Anyway, here is my list. Feel free to comment. :)
Log in to copy items to your own lists.
Star Trek (1966 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.4/10 X  
Captain James T. Kirk and the crew of the Starship Enterprise explore the galaxy and defend the United Federation of Planets. (50 mins.)
“ A cultural phenomenon that bridges generations, survives and thrives in reinterpretation (TNG, DS9, Enterprise) and invites reinvention. Exploration plus the human spirit divided by dilemma and action. It's an equation that still works, 46 years later and counting. ” - herreraster
Doctor Who (1963 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.5/10 X  
Time and Space traveling adventures of a Gallifreyan Time Lord only known as the Doctor and his companions, traveling through time and space. (45 mins.)
“ Doctor Who remains the longest-running science fiction program in history. Eleven actors have played The Doctor, all different incarnations of the same man thanks to the Time Lord's ability to regenerate. The shows over time have spanned virtually any kind of tale that can be told within science-fiction and beyond. ” - herreraster
The Twilight Zone (1959 TV Series)
    1 2 3 4 5 6 7 8 9 10 9.0/10 X  
Ordinary people find themselves in extraordinarily astounding situations, which they each try to solve in a remarkable manner. (51 mins.)
“ While the show was not popular at the very beginning, The Twilight Zone managed to draw attention to many science fiction ideas and authors, popularizing the genre and proving that it was something more than just fun or children stories. The show's popularity and legacy did not end with the conclusion of the series. The Twilight Zone was continued in different remakes and still is making its way into popular culture today. ” - herreraster
The X-Files (1993 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.7/10 X  
Two FBI agents, Fox Mulder the believer and Dana Scully the skeptic, investigate the strange and unexplained while hidden forces work to impede their efforts. (45 mins.)
“ The X-Files was groundbreaking because it married the familiar TV formula of the police procedural (FBI agents) with the fantastic (the search for extraterrestrial intelligence). It's been one of the longest-running shows of its kind due to the amazing storytelling and the solid chemistry of leads David Duchovny and Gillian Anderson. ” - herreraster
Lost (2004 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.4/10 X  
The survivors of a plane crash are forced to work together in order to survive on a seemingly deserted tropical island. (44 mins.)
“ LOST’s impact on the TV landscape can’t be denied. Before LOST, mysteries and cop shows dominated. Post-LOST? Okay,I won’t deny there’s still a lot of that, but the amount of serial dramas with mysterious and complex backstories, trying to ape the LOST formula is only increasing over time. Intelligently written, never afraid to change its basic premise, and with one of the best production teams on TV, LOST’s impact is undeniable, and it’s a show we’ll be discussing for decades to come. ” - herreraster
The Prisoner (1967 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.6/10 X  
After resigning, a secret agent is abducted and taken to what looks like an idyllic village, but is really a bizarre prison. His warders demand information. He gives them nothing, but only tries to escape. (50 mins.)
“ This British series is one of the most influential TV shows of all time – and chances are, you’ve never watched it. Without Patrick McGoohan’s ex-spy waking up in a strange Village, trying to work his way out, we’d never have gotten LOST, or pretty much any other mystery show that’s played on TV. The Prisoner still stands the test as one of the most fascinating TV puzzles ever made. ” - herreraster
Quantum Leap (1989 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.1/10 X  
Scientist Sam Beckett finds himself trapped in time--"leaping" into the body of a different person in a different time period each week. (60 mins.)
Director: John Cullum
“ For five seasons, the tale of Sam Beckett, trapped in time and just trying to make his way home was a delightful and fun exploration of different American time periods. But Quantum Leap operated on a greater premise. You had one scientist "leaping" into body after body across time, and his only companion was the holographic representation of a computer back home that only he could see. That's pretty high-concept sci-fi for TV, but it worked. Beautifully. Much of the credit goes to series leads Scott Bakula and Dean Stockwell, both of whom played drama and comedy in perfect pitch the whole time. ” - herreraster
Firefly (2002 TV Series)
    1 2 3 4 5 6 7 8 9 10 9.1/10 X  
Five hundred years in the future, a renegade crew aboard a small spacecraft tries to survive as they travel the unknown parts of the galaxy and evade warring factions as well as authority agents out to get them. (44 mins.)
“ Firefly posited a future universe that echoed today's political landscape but felt like a classic western. From the spare theme song to the presence of neither aliens nor sound in space, "Firefly" was all about the details. One of the best sci fi shows that ever graced our tv screens with lots and lots of potential for future brilliance. Unfortunaley Fox thought otherwise. ” - herreraster
Battlestar Galactica (2004 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.7/10 X  
When an old enemy, the Cylons, resurface and obliterate the 12 colonies, the crew of the aged Galactica protect a small civilian fleet - the last of humanity - as they journey toward the fabled 13th colony, Earth. (44 mins.)
“ David Eick and Ronald D. Moore’s Battlestar Galactica reboot was one of the most spectacular, depressing, claustrophobic, and well made shows on television. Though the mini-series was great, the first episode of the show, “33” is one of the best hours of television ever made. ” - herreraster
Babylon 5 (1994 TV Series)
    1 2 3 4 5 6 7 8 9 10 8.2/10 X  
A space station in neutral territory is the focus of a unique five year saga. (45 mins.)
“ Dealing with grand themes of war, sacrifice, and politics, Babylon 5 was a dark scifi show that featured a sustained narrative throughout the entire series. Debuting in 1993 at the height of "Trek" popularity, "Babylon 5" achieved an epic scope rarely ever attempted on television, with the fate of humanity and the galaxy itself decided upon by the end of its five-season story. ” - herreraster
