The Hangover was definitely the best movie of 2009. Such a great comedy i dont think ive laughed so hard since watching superbad lol no but there haven't been so many great new comedy's in the last couple of years the hangover is the best comedy in years.
The Hangover! I've watched it 3-4 times already. After checking out IMDB it looks like there will be a sequel in 2011.
