Demented is one of many nasty, sleazy rape and revenge themed horror movies that were churned out in regularity in the late 70's/early 80's. However, this is one that deserves to be forgotten about, which is surprising that Shout! Factory recently released this on blu ray. The storytelling and overall direction of the film is inept with very little character development or story. The acting is even worst, with the best acting from 70's porn actor Harold Reems, seriously. Sallee Elyse who plays his wife is a very attractive woman with enormous breasts and zero acting ability. Add to the fact that her voice is screachy and a stupid plot, this film truly is an endurance test for the audience to get to from beginning to end. The psychological aspects of the film are way out of our leading lady's ability to convey, or to emote at all in fact. Now our main character's fate is horrible, she gets gang raped and when she gets released from the mental hospital her husband ignores her and plays with his girl on the side and gets terrorized by neighbor hood boys that break into her house at night, thus driving her insane to kill everybody. Who would treat a rape victim that way? Demented is a sadistic, misogysist film that is so dumb and poorly executed it falls completely limp. A good example of a movie like this that works and is done well is I Spit On Your Grave(Yes, the original, but even the uninspired remake is much better than this!). Demented is a total piece of cinematic crap and is not recommended to anyone.
