I just got back from watching the Dark Knight and it was one of the finest movies I have ever seen of any genre. I was worried that the acclaim for Ledger's performance was largely due to his death (for the same reason that there are so many Freddie Mercury fanboys), but he deserves every ounce of praise he got. As an actor, Nicholson's accolades outstrip Ledger's by far, but as the Joker, Ledger blew Nicholson the **** away.
