For something with an IMDb keyword called "Cult Comedy", I really can't say that I laughed once during the whole movie. But I was smiling through most of it. Basically the whole movie concept was so unbelievable, it was a fairytale. Everything from living in Chinatown on a beautiful estate (laughable, if you've ever been to many Chinatown's in the world), to getting a disease that makes beautiful women want to kill you from eating paintchips, to being from a karate family in Chinatown (hehe), to being banished into the desert when you're a kid and eeking out a living by selling geodes on the road, to being attacked by an Indian tribe everyday while living in the desert, to that Indian tribe being a bunch of white guys in dime-store Indian outfits, to re-finding your true love via a car accident caused by your evil brother, to everything else in the movie... :) The writer even using the concept of eating paintchips when you're a kid and/or having an xray unit aimed at your groin for a long time ultimately causing mental retardation in your child.
All in all, makes for a mediocre comedic fairytale.
