I find your complaints about the current BSG interesting, since they're some of the aspects I like best about it.
I find the political aspect of the show more intriguing than most political shows on TV. I hate the original BSG and it's cheesy "adventure" - they took a very good, very dark concept and tried to kiddie it up and it failed miserably. And I love the ambiguity of the protagonists and antagonists - not as cut and dry and boring as most fiction.
And the series was finished last summer. Sci-Fi just wanted to drag it out as long as they could because, honestly, it's the only thing that gets them ratings anymore, and when it's gone, they'll be lost completely. I agree about the season sets to an extent, but when seasons are split up by that much time, they should be considered a separate season anyway IMO.
