I think only one strand of the show was disconnected, and part of me feels that if I go back and rewatch everything, it will become more connected. I think it's always a danger introducing anything at too late a stage as it takes up too much time thinking about how it connects (or gets bogged down in terrible exposition, which they at least avoided), but I really can't see how they could have done anything else. And in many ways, while unexpected, I think that this is probably the best of the available endings. Potentially.

In terms of the BSG finale, I don't think it's disconnected from the show as what it reveals is certainly in line with hints given throughout (although I found the Opera house reveal to be immensely literal). But I largely enjoyed it. Until the last 5 minutes, which still really really really really annoy me. I think it was a cheap shot unworthy of the show's general tone and content and was completely unnecessary and spoiled what went before.

And yes, I do watch Caprica. I really enjoy it (mostly - if they could get rid of Joseph, at least). This will be heresy but I can see it becoming better than BSG. So I will definitely be up for discussing it!
