The American Ruling Class Reviews
However let's get this straight, this movie is by no means a "classical" documentary. A better term to use would probably be molded documentary style storytelling. The movie is in the documentary tradition, however, the main characters are played by actors that interact in a landscape where some are aware of their role (other actors) and others are completly oblivious.
This really belongs in a genre all its own. If a more refined movie of this type was created, a filmmaker could easily create a believable and satisfying piece of cinema.
