First up is Troll 2 - which is an inexplicable title, as the movie contains no trolls. This movie is a diamond in the rough of bad movies, and has recently spawned a documentary: "Best Worst Movie".
Finally, there's Enter the Ninja. One of the dime-a-dozen samurai-sploitation movies that were pumped out in the 70's. We see in this powerhouse scene, however, that this one is a cut above the rest. Enjoy.
