Putting Laura Roslin over anyone but Tory is terrible. Every episode I raged about everything she said, everything she did and yeah I was generally pretty mad with her. Can't see the Sharon love either, she (and really the entire series) annoyed me with the LOOK HERA SHE'S SO IMPORTANT and she was just too hysteric for me to care about. Ellen and Cally so low is right, both amazingly annoying chars, though Ellen got more decent towards the end.
I singled out Gaius' Six because she was by far the most fascinating and interesting. The other Sixes were generally too awkward for my liking.
But I enjoyed this show a lot, though it did have plenty of problems (really bad episodes, the ending omg I mean Lost is my favourite show ever so I have no right to complain but BSG ending was really no explaining and random stuff EVERYWHERE) Also except for Will Adama no character really is awesome all the way through, like Lee is kinda bland and then becomes pretty wicked in season 4.
Also 1 is da best for being the most intense(you know nothing of Cylons and it's all exciting and my god that finale), then season 4 because aside from the first couple of episodes it's really good all the way through you keep wondering what's going to happen, and three and two are last because well hey, two had the worst BSG episodes so it gets last.
