I wouldn't take a young kid to see to see The Dark Knight. A kid who was 11 or 12, I don't think would be a problem. The absolute worst I remember was parents taking kids who had to be 4, 5, or 6 to see the South Park movie. Absolutely inexcuseable I thought and it was clear to me that the parents didn't care enough to read what was actually in that movie.
I'm looking forward to this movie. Though I really wish the media would quit with the Heath Ledger hard-on. I felt sorry about his death but give it a rest already. Here was a guy who died naked in an Olson twins apartment because he couldn't stop shoving pills down his throat. He gotten more tributes than most people who actually deserve it.
