Yesterday I was in the cinema, watching Fahrenheit 9/11. I have to say, I was really impressed. Contrary to "Bowling for Columbine", Michael Moore didn't put himself in the foreground, and except for two scenes (reading out loud the PATRIOT act from an ice cream wagon, asking senators to enlist their children to the Army), he doesn't do anything else funny or something like that. And AFAICR, there is only one other scene where he appears, and that is front of the Watergate hotel and the Saudi-Arabian embassy.
What I really like about Fahrenheit 9/11 is the well-researched relationship between the Bush family and the Bin Laden family, and the sometimes really rare filming he presented, e.g. the bomb attack on a group of GIs, the (uncensored) body desecration of the US-american mercenaries whose burnt bodies were hung up at some bridge, the countless pictures of dead and wounded Iraqi civilians, and the sometimes really shocking interviews with GIs, who found it "cool to fight with a catchy tune in their ears". So, in case you haven't seen the movie yet, do so. It already pays off for the closing music, Neil Young's original "Rocking in the Free World".
