“Conservatives do not have a reputation for making good documentaries, mainly because they do not have a reputation for making them at all.” But a fledgling movement is aiming to change that, as intensely conservative film festivals have begun to spring up around the country in response to the commercial success of left-wing films like Fahrenheit 9/11. Screenings frequently begin with group prayers and recitations of the Pledge of Allegiance, and the only thing the crowds seem to enjoy more than a good sympathetic portrait of President Bush is a film that carves up Michael Moore like a Thanksgiving turkey.
