Lots of over-the-top characters and bloody action in its ending sequence help make up for an overlong and complicated setup, but I think the film's wild humor came from a place I couldn't quite reach. If it was trying to saying something about filmmaking and violence it was beyond me, and I didn't see much humor in all the zaniness. If you're in the mood for something weird though, this might be your film.
