Isn't a season finale supposed to have some cliffhanger elements to it though? Part 2 of a 3 parter seems to fit that mold. I know what you are saying about the finale though. It would have been pretty sweet to see Cas and Rafael have a badass fight but how easily he was destroyed shows just how much power is in Cas. We also have no way of knowing how messed up Sam is going to be now that he remembers hell. I'd have liked more as well but I agree that it does set up some interesting plot lines for the next season.
