The cult favourite space Western only ran for one season, but that one season made a huge impact in terms of fan love and legacy. Starring Nathan Fillion, Gina Torres, Summer Glau, and more, the show takes place in a future where space is colonized by a super-alliance between the US and China and a failed rebellion has left our heroes working as mercenaries. The 2005 feature film follow-up, Serenity, failed to relaunch the show but continues to be a geek favourite.
