"Why things happen, such as the massacre at Columbine High School, especially in America?" Asks the makers of "Roger & Me" and begins with his camera crew of American society on the tooth to feel, in the registered more than 25 million Firearms are widespread and where there are more every year deaths by bullets is than in any other Western country. He talks with representatives of the arms industry, with students of the Columbine High School with weapons clubs and at the end even with Charlton Heston, the legendary actor and president of the US gun lobby, itself. In the colorful team of interlocutors, however, shock rocker Marilyn Manson and South Park creator and Columbine graduate Matt Stone are still among those whose contributions make the most sense. Mr. Moore is in every answer a new question and mostly it's just the right. It creates a so provocative as funny billing with the American gun culture, which is at its worst when it tries anyway to emotionalize disturbing circumstances in addition. His interview methods are not always flawless, especially as it provokes negative reactions of some him unlikable people directly. But still it can always capture the audience with humor and irony in the face of misery and manages to produce some terrible relationships. Probably the most important American film since "Schindler's List"!
