I LOVED the episode! Deb and I watched it again last night in the hotel, and we guffawed our way through it all over again. SO much fun - and I didn't see it as forcing Dean into being comic relief. Rather, I took it as little boy/uberfangeek Dean being thrust into his ultimate fantasy situation, and letting his silly side bloom. It didn't strike a wrong note for me at all. The only bit I didn't care for was Rachel, but they killed her, so I'm content.
