Teens should watch this film, because it does have some good points, but not everything in it is completely accurate. In an ideal world, we would have no need for guns or violence. But just because truly violent people have guns, it's no reason for others not to. After all, the violent people aren't going to be emotionally compelled to put away their weapons thanks to a Michael Moore documentary, so why should we? If we give up the guns, and they don't, aren't we just giving up our protection? And as for changing gun laws, one of the Columbine killers had the following to say in video footage: "Go ahead and change gun laws. How do you think we got ours?" They broke guns laws and bought their weapons illegally. This is a documentary about violence, so of course it's going to contain violent images, and there's some swearing as well. But even though I didn't always agree with this movie, I think that older teens should still watch it (as well as other films representing the other side) so that they may have their own informed opinion.
