I saw the midnight premiere last night, and what a fucking phenomenal movie. Rotten tomatoes only gives it a 73% by top critics, but that just goes to show how well sticks fit up the asses of the artistically "elite."
The ending was absolutely fantastic; I can't think of a better way to have wrapped it up. You must go see this movie.
