The Dark Knight is an excellent movie because of the mixture of action and psychology the writers and director Chris Nolan infused within it. At nearly two and half hours long, the movie hits a drag point at around two thirds of the way in, but the effective use of The Joker keeps the movie's pace from falling away. Every character is dealt with realistically (as far as comic book characters go) and there are some serious insights into the motivations of both Batman and The Joker. The creators took a risk with the highly serious content in the movie, but balanced it with the perfect amount of action / comic fan service. Despite thinking that the story would be straightforward, I was happily proven wrong with a wonderfully twisting plot line that rewards active viewers and successfully resolves any confusion (as far as I could tell). A fantastic movie that I will undoubtedly see twice or more in theaters. Heath Ledger is outstanding as The Joker, perfectly capturing the psychosis of the character, if psychosis is truly even what The Joker is suffering from. I will definitely purchase the special edition when it releases on DVD, which hopefully will have interviews with Ledger on his role as The Joker. A sequel more worthy than its predecessor, fans of Gotham City will not be disappointed in The Dark Knight.
