6. BATTLESTAR GALACTICA
What originally started out as a "Star Wars" cash-in back in the 70s was re-imagined as a paranoia-soaked Gulf War/War on Terror parable by executive producer Ronald D. Moore. Dark, complex, and mature, it pushed the boundaries of sci-fi TV and almost single-handedly legitimized the SyFy Channel. It also made Tricia Helfer the sexiest TV robot since Rosie on The Jetsons.
