I haven't seen the film myself yet but i'm going to as soon as it hits theaters and stores overseas. The topic mr Moore adresses in this movie is interesting indeed: "Is USA a nation of gun nuts or are they just plain nuts?" It's not supposed to be anti american or anti guns (Michael Moore himself is a NRA member and pro-guns). Give it a shot when it hits a theater near you and see for yourself. Check out the trailer on the site also.
