This movie was really dark. Heath Ledger's interpretation of the Joker was for the ages. The joker is a sick individual who likes to analyze and experiment on human morality. Throughout the movie he forces people to make tough decisions to test their moral fiber. Do you trust your fellow citizens to make the morally correct choice? That is the question he presents throughout the movie. His whole idea is to expose and test the corruption of Gotham.
The script was amazing. The dialog between Batman and the Joker where amazing. This movie had it all. I cannot wait for the third one.
