Just imagine the most awkward, cringe-iest person you know. Then cast an entire movie with dozens of them. This movie is so genius that the first few times I watched it I didn't know it they were acting or if it was some documentary from a town I never wanted to visit.
You feel guilty for laughing at poor Napoleon - he's that awkward kid that just doesn't know he's not normal. But his family and most of the people at his school are just as bad, Which is GREAT!
If fo some reason you've necer seen this movie - WATCH IT TONIGHT!!!!
