How bad is it? Pretty terrible even by 1960's soft-core standards.
Should you see it? It's only for Ed Wood fanatics.
Cashing in on the popularity of the Raquel Welch film "One Million Years B.C." and recycling some footage from "One Million B.C." (color-tinted), this was at least partly written by Ed Wood Jr. There's a virgin sacrifice that involves straight and lesbian sex, plus rape with dildo and it's really uncomfortable to watch. There's also rape by gorilla. There's a cat-fight to the death. The director has a cameo (hard to describe, but he has a typical porn 'stache of the time). The puppet from "The Mighty Gorga" is re-used and the one laugh is when a static plastic puppet is hunted with spears that fall woefully short. There's some very old jokes delivered poorly, but mostly this is just non-stop sex... also delivered poorly.
