In general, I really liked the whole series of BSG. However, the place where it fell down for me is where the religion stuff turned out to be true. Okay, that's a little harsh, but I really liked the way the religious stuff was ambiguous in the earlier part of the series. The whole final episode relied on the fact that the religious aspects of the show were true. And that bothered me.
The first hour of the finale was certainly exciting, but, even then, it was largely based on the idea that they had to rescue Hera, and that was based on nothing more than the notion that she was the salvation of both the Cylon and Human races.
The coda of the series, where it's "revealed" that the story was an anti-technology metaphor -- well, that's just irritating, especially since the exact opposite theme had been advanced throughout the last couple of seasons.
Largely, though, this stuff didn't bother me during the actual viewing of the finale. What did bother me was the schmaltziness of the last hour. I felt like they were all going to have a group hug and sing "It's a Long Way To Tipperary". And the idea of thirty thousand people all universally being okay with throwing away all their technology was just stupid. As was the notion of spreading them out all over the world.
Of course, the one thing that bothered me the most is that there was no way that "All Along the Watchtower" could already have been written. That's the single most anti-suspension-of-disbelief thing I've ever experienced in a TV show ever, and there was apparently no point to it other than someone on the production staff liked the song.
All that said, the finale would have been much better if they had miraculously found New Earth and decided to settle and just completely left out the denouement and coda.
