This movie was a a 1989 West German horror film. Somehow it has three sequels, and a movie reboot. But the original is so dated with computer effects and bad acting on top of horrible plot. The Rifftrax crew should tackle this at some point. Either a Rifftrax Live or just under Rifftrax. And they could call it Violent Stuff and try a blur for the title name on screen.
