I can agree. "Roger & Me" and "The Big One" were great documentaries about the people and how big companies do not care about them. GREAT movies!
When "Bowling for Columbine" came out, it wasn't very controversial, except about the Columbine video he used and was seen as a doc "Everyone should see." Than Bush attacked Iraq and all gloves were off.
Some people just hate other who have an outlet for their voice, be it Moore, or Mike North, or Jay Mariotti, or Jon Stewart.
