Wow. They definitely haven't done anything like this before. To be honest? I enjoyed it. There was some great brotherly goodness. Sam doing research on his laptop, "bitch" and "jerk", some good old back-and-forth banter, even some classic rock. Some of the stuff I'd really been missing from the show, and none of the annoying angels crap. It even wasn't so heavy on the myth arc stuff, and by that I mean not a lot involving the demons/Crowley/Rowena. Felt more like an old school type of episode.
I thought Dean's phone convo with Cas (when the monster guy was tackling him) seemed to drag on a bit much but maybe that's just me. I did LOL after Dean chopped the guy's head off and then whacked it off the windshield with the wipers.
The stupid girl working at the steakhouse who took off with Baby...geez, idiot. But wouldn't the boys have seen her speeding away like that? Or was it too hard to tell from that vantage? They didn't seem to bat an eyelash when she came back.
Yay for the car-washing scene in the beginning, though it would've been nice to see them shirtless ;)
And then Sam's dream/vision or whatever featuring John (Matt Cohen as young John...I wasn't that surprised, I could tell it was him based on one of the promo videos for this episode). I'm with Sam, what was that about? Who was giving him this vision, and saying he and Dean are the only ones who can stop the darkness? And especially that "God helps those who help themselves" quote? Might we learn more about this later?
Oh and one last thing...Sam with that waitress! Hee...bout time we see him getting some lovin' ;)
So yeah, initial reaction is that I really liked it. Nice little break from all the really heavy stuff I'm guessing we'll expect at some point. Next week's ep looks interesting too, especially since it's a subject I'm very familiar with.
