20 Greatest Sci-Fi TV Shows

7. FIREFLY
(2002)
In 2002, Buffy the Vampire Slayer creator Joss Whedon attempted to reinvent the space opera with a rough-and- tumble vision of the future set in an Earth-colonized galaxy. Part Western, part sci-fi, wholly unique, Firefly starred Nathan Fillion as the captain of Serenity, one of those dumpy old ships that don't look like much but get the job done. The TV series tracked the misadventures of his morally ambiguous crew as they tried to make an occasionally honest living by hauling cargo, stealing stuff, and accidentally helping their fellow man. The show was smart, funny, and wonderfully human, and because this is Joss Whedon we're talking about, it also had a highkicking, superpowered wonder woman. Firefly was strange. Firefly shouldn't have worked. And it didn't. Firefly was canceled after 11 episodes. Stupid Fox. —Jeff Jensen
