Midnight showing it wasn't too bad - definitely packed.
Some kid in front of me (looked like a Soph in college) thought he was real clever and said something after every preview very loudly until I kicked the shit out of the back of his chair.
He didn't even turn around and was quiet as a mouse the rest of the time.
I showed up at 4:30p to see the 4:45 show opening day and we found seats.
Crowd has been pumped at all three showings - clapping etc.
