What makes it different from others?

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

One of the worst ways to make a cult movie is to set out to make a cult movie.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.
