I suggest not watching anything past the New Caprica arc.
I'm still watching the season. BSG is a weird watch for me. There is a lot of stuff I like, but it seems like for everything I like, there is something that is either downright annoying or just not very well done. I don't regret watching it, and I do intend to finish the show, but I doubt I'll be rewatching BSG anytime soon 9or watching the spin offs). At this point,
I just really want to know what happens. I'm really interested in the last 5 cylon thing, and what will happen to them (and who the fifth one is). I'm also interested to see how the show ends, and if they make it to Earth.
That said, I'm beyond done with gaius baltar, religious icon. I pretty much tune out his sections at this point, its easily the worst stuff in the show. Turning the president into a power grabing, very undemocratic seeming person is just bizarre and being hammered in a bit too much. Lee has become a very unlikeable character, but he doesn't get much screen time, so its not a huge deal.
I do have some complaints, but I'll definately finish the show. I think BSG is, to me, a show that had an interesting premise, some cool and interesting concepts, but has a lot of flaws, with the religious stuff being used WAY too much and with Baltar being almost infuriatingly annoying since New caprica. Not a bad show, but a flawed show that I think could have been better.
Also, I have definately decided to skip Razor. I might watch the plan (I picked it up for $1 awhile ago) but it will be whenever I feel like it.
