There are certain limits you can push socio-political analysis before it starts to overshadow the rest of the show. Yes, I do think BSG does a far better job than the original in portraying the human condition of what happened, rather than the 'Ooops!' reaction from the Original.
However, I was willing to accept that the first series was going to to be all run and little fight, but I would like to see a little more combat action, it doesn't cost any more money to render more ships, you have one model and that's all you need. Though it would introduce time constraints for more ships/explosions etc, when you are talking Vipers vs Raiders etc, it's not like you need to pay for new models, and the animators aren't paid on a 'per explosion' basis

But this is a Sci-Fi series, with a Battlestar, an old, but deadly warhorse, it'd be nice to see if properly go into action more often.
I've only watched series one and my total impression was, very good, very dark, and I wish Boltar would shut up sometimes.
Finally, as far as personality transference goes, we aren't entirely sure how it works, Cylon raiders are techno-organic, they may view each cylon's experiences as a 'Soul' that they pass into another shell, it may possibly be against their religion to duplicate 'souls' like that?
