Well, at least this movie doesn't wast too much time on boring introductions or overlong mood-settings. The opening shows a woman caressing her favorite horse for only a brief moment, and the very next second she's assaulted by four sleazebags with stockings over their heads and gang-raped in the stable. This scene is rather short and unclear to watch, yet also rather unsettling because these guys just 'come & go' without even bothering to take their disguise off. A certain period of time later, Linda is released from the mental hospital but definitely not cured yet. Her unfaithful husband (Harry Reems the porn king) is spending most of his time with his mistress and Linda slowly goes...well...demented! When a new gang of thugs attempts to rape her, she snaps for good. "Demented" is a typical rip off of Wes Craven's "Last House on the Left" but tries to add a (lame) psychological theme. Linda avenges herself and cuts up people with a meat clever, only supposedly she's in a totally different state of mind. Whatever. It's a really lame movie, with only a few suspenseful moments and a disappointingly low amount of gore and sleaze. There's the obligatory castration-sequence thank you "I Spit on your Grave" but you can hardly make out what's happening. Sallee Young and Kathryn Clayton are ravishing ladies, but not exactly great actresses. Give "Demented" a miss and aim for one of the thousand other underrated rape & revenge films out there, like "Last House on the Beach", "Night Train Murders", "House on the Edge of the Park" or "Fight for your Life".
