The first film that I saw at the Atlantic Film Festival was Michael Moore’s latest, “Bowling for Columbine.” A entertaining, at times funny, at times chilling examination of gun culture. It features a great opening sequence at a bank in northern Michigan where you get a free gun when you open an account. Other parts aren’t as effective, but Moore seems to strike just about the right balance between the funny and the serious to look at things outside of the mainstream view. Worth seeing and discussing.
