Caricatures instead of characters
The problem with this film is that it's so over the top, with such one dimensional characters, that they end up being caricatures instead -- with ONE feature over-emphasized above and beyond everything else. This movie had some potential, although the theme has already been hackneyed to death. But it still had a chance. Unfortunately, it wasn't handled well enough to pull it off.
