The body swap idea has been done before ("Luck Key" comes to mind), so while the story is not really original, it's still a funny movie. The greatest part is the total character change of the fat and shy highschool loser after having absorbed the gangster boss' personality. Really shows that even a fat kid with thick rimmed glasses can be a total alpha male when he carries himself that way. Absolutely hilarous. The movie is kind of stupid and childish at times and it could have been 15 minutes shorter, but ultimately I enjoyed it and had quite a few good laughs.
