The problem with Moore is not his movies. They are actually well-crafted and funny and he can do or say whatever the hell he wants for as long as he wants because it's a right we enjoy as Americans. The problem is he calls his movies 'documentaries,' when they clearly are not. A documentary is a non-biased film based upon factual evidence. Moore's films are completely biased and are very lax when it comes to factual obligation as Djaughe's previous post illustrated.
Fahrenheit 9/11, with its release date prior to the elections and Moore's admittal that the movie should effect the way people vote, actually fits into the category of propaganda.
propaganda
1. the deliberate attempt by some individual or group to form, control, or alter the attitudes of other groups by the use of instruments of communication, with the intention that in any given situation the reaction of those so influenced will be that desired by the propagandist.
2. information that is spread for the purpose of promoting some cause (in this case; not voting for George Bush and co.)
documentary
1. Presenting facts objectively without editorializing or inserting fictional matter, as in a book or film.
We need to be careful in discussing this film because in my opinion, it does not fit into the genre that the filmmaker intends.
