The Dark Knight
DIRECTED BY CHRISTOPHER NOLAN
Why's it so good? Christopher Nolan's special genius lies in building his comic book films around a theme and making them stronger for that. The theme of Batman Begins was a city's response to fear (good drinking game: count the uses of that word / variations on it during Begins). This time, it's about the fine balance in our lives between control and chaos. Oh, and Heath Ledger's Joker perfect balances Bale's fiercely controlled Dark Knight.
