Query: A Casting Masterpiece

Every character in this movie is flawlessly cast, and relatively unknown. The acting is superb, and the storyline is very funny. If you like smart ironic humor, you will love this movie. If you're neither smart nor ironic, you'll probably miss the point.Anyone from a rural background went to school with these people. It is like reliving your teenage hood.I couldn't help but notice how the reviews alternate from five stars to one star with hardly any middle ground. Like all great movies, this one has stirred up controversy.
