I think I amicably disagree with you, RF. I was actually more impressed with Heath ledger than I was with the great Javier Bardem. Heath scared you and made you laugh at the same time. He was perfect. He threw himself into the part like Javier did, but while Bardem had quiet moments, he had loud ones, ones where the Joker thought of himself as a comedy star, which in my opinion is harder to pull off.
