I saw TDK at a Midnight showing the morning of the day it came out (or the night before the day it came out, depending on how you want to look at it.
) And it was one of those rare "theater experiences" that you just cannot get that often. Everyone in the nearly sold-out theater loved the movie and the cheering/applauding that happened afterwards was great. The guy I sat next to in the theater him and I chatted quite a bit too about some Batman lore, and other comic-book stuff. Just an fun experience overall.
It's a movie that's really just nearly flawless.
