A violent rape gets a woman institutionalised and later suffering from PTSD with constant nightmares in Demented, one of the revenge exploitation movies done in the vein of I Spit on Your Grave.
And it’s not a strong show. Demented feels quite a lot like an early 80s porn movie, and a brief Googling soon reveals why: The male lead Harry Reems was one of the most well known porn actors of the time.
Despite the grave theme the movie is bit on a boring side with most of the interest in waiting on how the husband’s gaming with his extramarital affair plays out. There’s a slight payback in the end for sticking around as the movie gets pretty absurd and wanders deep into the black comedy territory.
