I pretty much never go to the movies either, I just saw Batman because my friend took me. The watchmen trailer made me want to see that movie, though, so there's that. I think the stepbrothers movie will make money, although god knows I agree with you about Will Ferrell. I think he's hilarious sometimes, but the Will Ferrell Movie is getting a little old at this point.
We didn't have too many previews, though. Just the world's shortest HP teaser (it said harry potter on the screen, basically) Watchmen and I think maybe one other thing. Short and sweet. The movie itself is god damn long enough as it is.
