The movie itself was good. The action was exciting and many parts of it had me on the edge of my seat. The filming itself was beautiful, the music was good, and the ensemble was great. But Heath Ledger is what made this film. He stole every scene he was in, he was frightening and interesting, and when he wasn't on screen most people were impatiently waiting for him to come back. You forgot it was Heath Ledger you were watching after the first three minutes. He obviously delve deep to get this character, because it overtakes everyone and everything in the film to make the most chilling, interesting, and amazing villain of any Superhero movie.
