As fans of shows such as Monarch: Legacy of Monsters (which finaled in January and is awaiting word on a possible Season 2) hold out hope for renewal, we must remember that the genre of TV that most often seems to be given short shrift is sci-fi.

The Nathan Fillion-captained Firefly — arguably the “poster child” example — lasted but 14 episodes on Fox, yet it lands high on list after list of “Gone Too Soon” TV shows. What other short-lived sci-fi fare ranks up there alongside Captain Tightpants, in that they made a lasting impression with their fleeting runs?

Below, the TVLine staff has rounded up and ranked the 15 best sci-fi shows that only saw the light of day for a single season.

Guided by the tenet that the elements of science fiction include time travel, teleportation, mind control, aliens, mutants, space travel, parallel universes, fictional worlds, alt histories, speculative technology and/or superintelligent computers and robots, our list highlights a mind-bending NBC drama that too many slept on, a Battlestar Galactica offshoot, The X-Files‘ spooky sire and more.

Plus, wherever possible (and done legally), we have noted where you can stream/rent/purchase these well-remembered sci-fi series.

Review our list, then hit comments with the sci-fi shows whose snuffings-after-a-season still sting you — or add suggestions of your own!
