Based on the diabolical doings of psycho-mama's boy Ed Gein, this film is guaranteed to leave you feeling uneasy for days after viewing. Some images are so horrific that they are fairly certain to haunt your dreams. Character actor Roberts Blossom in his best role ever is chillingly good as the overly devoted son who, not quite all there to begin with, goes completely round the bend when his beloved mother dies. He digs the old lady up, brings her back to the family farm, restores her corpse, and kills an occasional female passerby to keep her company. It's every bit as strange as it sounds. But when it's over, you can't simply shrug it off and say to yourself, "Oh well, it's only a movie", because it's based on the truth. Viewers familiar with the Ed Gein case will note that the filmmakers have, for the most part, stuck close to the facts. It leaves a strong impression, and, to put it mildly, a rather disturbing one. What's truly amazing is that the filmmakers have brought a sense of humor to these gruesome events and it ISN'T offensive. DERANGED is one of the best scary/funny movies I have ever seen. It is most definitely not for children. As for the adults, you"ll just have to take your chances.
