For four seasons, this ambitious space-opera remake was about character and morality in extremis: what could humanity do to save itself from annihilation? The gripping final run of the series brought Galactica and crew to the dark edge of destruction supplies dwindling, the ship literally falling apart before finding a way to the future that relied on what was best in humanity (and in the humanlike Cylons humanity created and warred with). The finale didn't satisfy everyone; the resolution, in which the human survivors agreed to give up their technology after finding Earth, seemed forced, and the last moments too preachy. But given the impossibly tall order of resolving the immense questions the series took on, its closing hours did a great job of satisfying both the head and the gut. Lost's finale next year should be so lucky.
