Season 3 was some of the most riveting television I have ever watched. I’m a bit of a sucker but I still really liked Season 4 despite its pacing, it was a victim of the writers strike.

I didn't care for their implication that we don't have a clear chain of human evolution in a sci-fi show but I also didn't expect that much from a series that had a running and viable theory that Cylonism was an STD.

Yeah. I was going to expand on that in the comment and decided not to for brevity.

It was only in the final two episodes that the timeline is established and it was the final two episodes that annoyed a lot of fans.
