The original was fun and I loved Dirk Benedict in just about everything he did (even the little known movie he was in where he played a 'Rambo' esque war veteran coming home to a harsh welcome). I liked Lorne Greene - his bearing and voice well portrayed a good leader character I think. And everyone loved Vipers, Raiders and the Galactica itself. Some of the disco moments and music do not improve the re-watching. And the episode with the devil (Iblis?) was a bit odd to my thinking. Did love the Eastern Alliance destroyers and the destroyer Captain they captured.
But let's talk about where that fell off the rails:
Battlestar Galactica 1980 anyone?
(Bleach for my minds-eye please!)
