Yeah, in particular, I like how they had to retcon that Hotdog was the real father of Tyrol and Callie's kid so that there would be only one human/Cylon child. It felt to me like that, in particular, exposed that they didn't know Tyrol was going to be a Cylon and they didn't know that the human/Cylon offspring were going to be important.

(As an aside, it sure would be nice if they hadn't inexplicably used the term "hybrid" to refer to the Basestar controller Cylons, so that I could intelligibly and correctly refer to Hera as a hybrid.)
