1967 Argentine Sci-Fi/Nudie Exploitation pic is utterly ridiculous/stupid if you're actually paying attention to it. From the time when low-budget Sci-Fi films had monsters wearing obviously cheap masks. To make this more marketable, the U.S. distributor added 17 minutes of basic, typical-for-the-time sex scenes. I can't say it helps, but I did watch it all the way through. The trailer's better if you can find that..
