We now refer to those simply as "documentaries".I was specifically addressing the merits of the film itself. Which has none. Agenda based propaganda films are not interested in truth. They have one goal, and that is to influence ill informed reactionary people. They use incomplete, outdated, and/or factually incorrect information to push their agenda. When they do that, they have zero credibility, and everything included is suspect.
You will be a smarter person if you ignore this type of media.
