I just got back from seeing The Dark Knight. eh... My first reaction was that it is over-hyped and if Heath Ledger were still alive there wouldn't be any mention of Oscar nominations (but people would still think he was a great Joker).
Maybe I'll feel different once the whole experience sinks in a little.
EDIT: As of right now I liked Batman Begins much more.
You crazy.

If you have an IMAX around you, I recommend going to see it there.
