How bad is it? It's Wild Women of Wongo and Dinosaur Island with an even smaller budget.
Should you see it? If you're a fan of cavewomen movies.
I've tried tracking down some of Don Glut's early films, like "Dragstrip Dracula" (1962) - short of actually contacting him and asking for a copy - but his later films probably aren't much different from his teenage endeavors. In this, a magic amulet transports a man back in time to just before women learned how to securely fasten their fur bras. Bras fall off A LOT in this film. There's stop-motion dinosaurs, poor green-screen effects, lame music [Glut sings two songs], the presence of Karen Black and William Marshall and a lot of silicone and heavy make-up. Mostly, though, there's unfunny slapstick jokes that Glut tried to punch up with sound effects.
