I have just watched this movie and I've got to say that I am quite impressed, up until 3/4 of the film. The movie serves as a parody to the present day American pop-culture, the society and the people, with a twist of dark comedy. The movie serves as a montage of how warped the people's mentality has become, how they have been accustomed to what used to be unacceptable and how un-civilization has became a trend.. because it sells.
The lead character blurts out quite a lot of sensible statements as the story progresses, that makes me want to jot it down and paraphrase, only to say "yes, it's exactly what it is"
Let's burn the bridge when we get there.
