Twisted Nerve is a rather well made film that deals with the psychopathology of a 21 year old man. His illness is "triggered" when he leaves his troubled home (a rich demanding father and infantilizing mother) to live as a border in the home of a college student (Haley Mills) and her mother (Billie Whitelaw).
The film works especially well when his sexuality is aroused by both Haley Mills and Billie Whitelaw, with disastrous results.
The movie takes its time to unfold. Although it does have some shocking scenes, this film isn't your typical slasher/psycho movie, as the advertisements suggest, its much more than that.
