My DH bought it since we "had" to complete our BSG collection. We really liked it.
Please note there are spoilers ahead. I don't know how to do the black line thingy, so don't scroll down, if you don't want to know some key points.
It was so freaky how there were sooooo many cylons on Galactica. It wasn't just Boomer. That was one of the interesting parts.
We thought the message was that the "Plan" didn't work out so well because a lot of the key cylon players ended up loving humans and didn't want to see them annihilated. Even the one Cavill ended up starting to like/pity that little boy, that's why he killed him, right?
