I just saw it tonight, and WOW. I really want to see it again, and I think I probably will. I agree, Heath really seemed to be having a great time. Not that he was at all recognizable as Heath or anything.

Trivia fact I just learned tonight: My friend that I saw it with just got back from a music production internship at Warner Bros. She said that they used two different composers for the movie, one for Batman and one for Joker. Even if I didn't want to see it again anyway, it would be worth it to me to go again just to try to listen to the music more.
