IGN - The Hangover Part II. An interesting title if you think about it. Part II implies this is the second chapter or second act of a much longer story. And in some regard, while the film is ostensibly a rehash of the first Hangover, underneath there is a much darker undercurrent, and a curiously existential examination of events in the first film. Alas, that's not exactly what many fans were hoping for with this dark, ugly little sequel.
