Batman The Dark Knight Sucks?

Although there is so much hype, the movie doesnt live up to it. I saw an advanced screening of it and it sucked. Heath ledger's performance was almost laughable. He tried to act all jokingly but in the end it was horrendous. I want to get my 10 bucks back. It was like watching an amateur film with ten year olds. DO NOT GO SEE THIS MOVIE!!!!!!
