I saw this at an IMAX theater and it was incredible. I felt like I was standing on the edge of the buildings with Batman. Initially I was concerned over all the hype about Keith Ledger and his acting. I have always liked him as an actor but maybe all this praise was sympathy. However, I found his acting in this movie to be chilling, hypnotizing and beyond what I expected. It was an amazing performance that kept you on the edge of your seat. I wish he had been in more of the movie. Excellent, excellent move!
