I gotta rise to B5's defense here. You make a fair point about how B5 had to rush the end of season 4 - then expand the beginning of season 5. And yes the "flow" of the series suffered for it. I also got tired of the Byron messiah crap for a while, however as a friend recently reminded me, season 5's schedule was way out of wack so many of the early season 5 episodes were aired several times before the final episodes were produced and aired.
Yeah the end of season 5 was actually the end of season 4. "Sleeping in the Light" I believe it was called, where they end the station and Ivanova gets a Warlock command and Sheridan goes off on his pony ride or whatever. Yeah that was a good end, but it wasn't really season 5. I don't remember barely anything from season 5, probably because I've only watched it once. And Lyta? Bleah. I don't know why all the guys got the hots for that chick. She was always one of the least desirable women on the show, I'd a preferred the blonde telepath to her. Not that there's anything wrong with Lyta, but there's nothing particular great either.
Laura Roslyn's fate made sense. But Admiral Adama and the Chief?? Please. Baltar and Caprica?? And their "angel" counterparts?? What's up with that. The Colonials voluntarily shucking civilization on Lee Adama's whim?? Sorry, I don't buy it. And don't even get me started on Starbucks fate.
Well. Baltar finally grew a pair. Did something selfless for once in his life. Put himself on the line instead of running. I think Caprica and Baltar should've had a little more contact before that, they didn't build up their reunion enough. But I'd buy that. As for Galen??
Think about it. He hooks up with Tori 2000 years ago, Tori kills his wife of the present day (Kali), Kali killed his first love (Boomer), Boomer did ALL KINDS of bad shit though redeemed herself in the end. I mean, a guy with that sort of streak with love? I think he's just done with women. Wants to go off and die by himself. He loved boomer, he loved Kali at one point and way back when he loved Tori but they're all dead. So what's he going to do? Grab a new woman somewhere? I think they're just making it clear he wants to die alone sorta thing.
As for the colonies thing. I dunno. New Caprica was a hole. I wouldn't want to live in another place like that. And really what technology do they have? They basically just have a bunch of ships with them, I don't think any of those ships are construction ships. It's not like they have pavers and constructions materials or whatnot. It's just like ditching your car after a really really long drive. It's a bit of a stretch, but, if you're living in a ship for 3 years breathing bad air and eating crap rations and someone asks you to leave it all behind in exchange for a new chance on some beautiful planet, I'd see a lot of people saying yes.
As for the other cylons. I dunno Cabal is dead. Presumably there's a few baseships lying around. But, how would they find them? Those cylons are just going to die off because they dont have resurrection tech. The only reason they had new caprica is because someone set off a nuke.
Speak of resurrection. The problem Cabal has isn't that they lost resurrection, it's that they pissed off all the women. They put deanna in a box, and the sixes and eights were against them. You want to keep the species going? Don't have only guy friends hahahaha.
