Is The Dark Knight the greatest super-hero movie ever?

Yes. I saw it today, and it is now my favorite movie of all time. In Batman Begins, you focus on Christian Bale. Yeah, Heath Ledger wasn't havin' that. He completely overshadows everything, and you can't wait for the next scene he's in. I NEVER like actors or actresses, I always thought it was just them talking, but this movie has proved me wrong. What's your opinion?
