Saw Dark Knight last night. I was very pleased with the movie. It totally blew the original (Michael Keaton) Batman out of the water. All the Ledger hype was true, you really couldn't tell that it was Heath. As for the villain in the next movie, it looked like the Nolans wanted to keeping writing in the joker, but I really don't think anyone could keep the role going so it almost has to be the Penguin.
