Heath Ledger almost stole the show in batman.
Iron Man was just incredible thanks to Robert Downey Jr.
Tina Fey? Not even in the same league as these two.
I agree, Ledger was spectacular in Dark Knight, and Downey Jr. was awesome as well. I think viewers (libs) flocked to the Palin sketches because they could not handle the reality that Palin is a political force. This drove them to seek asylum from reality, and herego they watched Fey on SNL and suddenly felt better about themselves.
