At first I was a little skeptical about Civil War with the big cast, but the trailers and everything the directors said before (I'm trying not read/watch anything now) really does sound epic.

I think for a lot of people it's shipping him with Dean. They see subtext in every scene they share and I'm sitting here thinking "What? Where you getting that from???"
He was a great addition at the beginning, but after two or three seasons I really had enough of him. I have to say that even though I like Crowley, he's also been on the show for a little too long by now.
