There is no way this movie deserves the five stars it's being given. I saw this movie back in the mid-to-late 1970s on late-night cable TV, it was a budget movie then, it still is a budget movie. The storyline goes this way, two insane brothers and their crazy mother kidnap teenage schoolgirls and keep them in the basement in order to play sick sadistic games on them. If you like sick sleazy sadistic exploitation movies then you might give this one three stars. In my opinion it deserves less than two stars, it's not bad enough to become a cult classic like "attack of the killer tomatoes" and not good enough to be on the same level as "last House on the left".
