It over explained things that didn't need to be explained. Seeing some of the events that were so beautiful as mysteries, played out as really generic attempts at making a seemingly quickly hatched together plan work... just stripped away all the dark coolness of the series.
It also made the cylons seem foolish. I was hoping to see the genesis of the original cylons who then left Earth etc and to then see how that played out. Instead, it was this weirdly paced episode about John's fantasy to bang his mom.
I felt the only character that worked in "The Plan" was Sam. His story was believable and likable and the actor seemed to be giving his all. I just didn't feel that with the other characters. For me, it was the worst case scenario. I recommend anyone who loved BSG skip "The Plan" in case it ruins the whole experience for you just seeing it. There is nothing in there that you HAVE TO see.
