The movie revolves around a brother and sister, and nothing in their lives interests them except sex. The brother says something conventional about how he's young enough to be anything he wants to be, but he shows no sign of wanting to be anything, or even having any interesting abilities. We have no reason to like them, unless we admire them for being edgy enough to have incestuous sex. They meet a number of other people who declaim monologues-- sometimes straight at the camera-- which are either also about sex or about what's wrong with their lives. None of this engages the audience, because the characters appear to be right: their lives are a waste.
