I know I am probably beating a dead horse, but Samurai Cop is the greatest terrible movie ever made. It is transcendental in its badness. Its an example of how cocaine can effect creativity when it's a principal factor in the production of a movie from inception to release.

Now you can watch that youtube clip, or you can enjoy the film unspoiled and have an anuerysm. I implore anyone who enjoys really bad films, and who hasn't heard of this one to watch it, and it's double feature companion: Hollywood Cop.
