The Dark Knight (2008)

There are quite a lot of visual effects in this film, most of them done well, but some fall a little short and look clearly artificial, especially in the two-face villain. An extreme but diverting application of Prisoner's dilemma in one plot point to very memorable effect -- "I'm going to do what you all should have done ten minutes ago..." Heath Ledger does an fine, almost unbelievable, job as Joker. He breaks the spooky/crazy meter with his voice in delivering the line: "Whyyy sooo seeerious??!"
