Los violadores

Pretty basic low budget revenge exploitation flick only notable for it's extremely high body count, and a novel "Nazi bikers vs Karate students" chopsocky battle. Unfortunately, it also features way too much frontal male nudity (including several closeups of Jess Franco regular Eric Falk's junk), and possibly the stupidest ending to any film ever made.

This has all the food groups. Even the ones you're not suppose to partake in anymore. ---- Homer : Well, we didn't get any money, but Mr. Burns got what he wanted. Marge, I'm confused. Is this a happy ending or a sad ending? Marge : It's an ending, that's enough

Not even fun bad, just bad bad.
