This movie creates a wonderful new premise for movie-goers. The Hangover begins with the usual character introductions, but then something amazing happens...15 minutes into the movie, you are transported to the end with no idea how you got there. The characters have to figure out what happened the night before, and the hilarity ensues!! This movie re-invents story telling with so much humor that your sides are aching by the time the credits roll! Just realize that it is Rated R, so don't take the kids...BUT, The Hangover is the best $17.00 I have spent in a long time!!!!
