I have seen this movie twice already and nothing and no one will be able to live up to Heath Ledger's performance as the Joker. If someone envisioned what the character of the Joker looked like on screen, this would be it. From his creepy laugh to "why so serious" tone, Heath keeps you hooked throughout the entire movie. This movie lives up perfectly to all of the hype it received and it does not surprise me that Oscar nominations are already being talked about. It seems like The Dark Knight could have been a movie just about the Joker alone, but the fight between Batman and the Joker is classic and it's true that Batman "completes" the Joker, as he says during the movie. I would recommend everyone to go see this amazing movie.
