Great series, but definitely not their finest season. The first few episodes which detail the Cylons invasion of the humans newly settled planet, New Caprica, are quite engaging. It captures a very believable struggle between what each side considers right and wrong during a hostile, yet supposedly beneficial, military occupation.
Towards the middle of the season, they move towards filler-like episodes which do not largely affect the overall main plot-line, and subsequently lost quite a bit of my level of interest. However, the last few episodes of the set recapture the intrigue and excitement of the majority of the show really making me anxious to get my hands on the final season.
