I might be 15 but actually i watched this on the plane without realising it was R rated ..... oh well. But although i'm quite innosent i didnt find it that disturbing. I agree there are drug and sex scenes but they are brief and non revealing and there is no violence at all. There is nothing light-hearted or childish abouth the film either. The movie has a overall sad aspect to it, with it's disturbed characters, and their sick actions and thoughts. The plot is mainly about these screwed up outcasts, one fat, one wild and volatile, and one damaged girl who all become friends. Apart from that and a few adversitys nothing much happens. But the way each character endures their own journey is subtle and moving. It is a really good movie if you appreciate the subtle and full meaning of it, and thats why I think it was made for older audiences.
