I just came from the movie and it was really really good. Ledger's Joker is the defining rendition of the character. I have never really been too convinced by Nicholson's rendition but Heath Ledger turns in an Academy Award worthy performance that should win and would definitely win if he were still with us. His Joker was terrifyingly evil and convincing--he totally owns the role and it's a tragedy he won't be able to reprise it in another Batman movie. AWESOME is the only word to describe it--he stole the movie from Christian Bale and the special effects (which were very cool) and it's beyond tragic that he's no longer here.
