I never knew Mr. Ledger. I never saw any movie or magazine that I knew to be a photo of him or featuring him. I saw A Clockwork Orange and did not like it particularly but recognized that looking at the depravity of the main character was a scary statement of who we could be. That was appealing to me. So in Batman, Ledger gives us a treat as to how sick a mind could act. He was phenominal. The rest of the movie was much less although I appreciated the attempt to discuss the big issue of vigilanties in a society seeking to have the rule of law. Frankly, when Batman is discussing the role of law in society, the dialogue felt preachy. More interesting to me was that when society was tested, it responded ... (you will have to see it). We sat in the back row and I still had a headache. I wish the theatres would keep it down a bit. Finally, a thought for the movie theatres - sell set seats in advance on line and structure the charges based on the quality of the seats. You could even sell the option to upgrade to a different seat.
