OK, the season begins. So this first episode is all set-up. Interesting start. Loved the use of Metallica in the intro. I was a bit surprised that Castiel didn't come back this episode. Will Chuck answer Dean's prayer and put Cas back together from the ashes? How long until Jack goes nuclear? Will we see Alt-Universe Bobby again? God (er, Chuck?) I sure hope so. I'm hoping this story-line has a bit more going for it. Again, all set-up, but I want to see more.
