Go figure! How can the same movie be rated G in Canada and rated R in the US. Clearly something is wrong. First off, the movie is a "pull no punch documentary about bullying" the language is "frank" and the imagery is difficult. The thematic is particularly troubling since it deals with something we have all at the very least all seen (or worse suffered).
For some reason a frank analysis of a huge problem for children in North America -- maybe cathartic to children suffering from bullying and may even make those who "tax" think hard about their action is seen as something unacceptable for American children to see.
Sad and amazing
