The satire is mean and savage. Even the names are odd. DeVito's character is named Chief Rash. The Dearly family members are all nasty. And so on.
People do strange, unexplained things in the movie.
Curtis, who dresses like a hag and looks like one of the witches from Macbeth, has sexual adventures with both Fichtner and Thomas. Don't forget they play father and son. Each liaison involves a Wheel Of Fortune board game. The trouble with this kind of humour is that it is damned difficult to sustain over the length of a feature film. Gomez, pushing Peter Steinfeld's script to extremes, can't keep up the pace or maintain the mood.
