The ultimate science fiction war series. Unafraid of taking risks nor deleting characters that had run their course. Fantastic acted with thoughtful and riveting writing. Effects and action that kept one's attention. It really felt like it had a planned story to tell all the time with a definitive ending that may not be perfect for everyone but worked beautifully for me.
I really try not to judge a book / film / series based on its ending, but it's been at least five years since I watched Battlestar Galactica and the moronic season finale still haunts me to this day. If you want to save your respect for the show, don't watch the last episode!
