This remake took a corny Star Wars knockoff from the ’70s and turned it into a piercing look at morality, faith and what it means to be human. It also featured some of the most kick-ass, mind-blowing sci-fi on a small screen in the decade. As the remnants of humanity were chased by human-like Cylon robots, they didn’t just explore the universe in their search for survival. They explored their own history, discovering the twists that led human and Cylon to develop as parallel and intertwined races. And BSGalso — with its stories of hidden enemies and religious conflict — told a relevant story for the post-9/11 era that kept this space saga grippingly grounded.
