I saw this film years ago and can vaguely remember it - one thing that does stick in my mind is the appalling rape scene. Two guys who live in a seedy apartment put an advert in a window for a 'female flatmate'. A girl comes along and when she meets the two guys and sees the state of the flat she quickly tries to leave, but is stopped, forced to the floor and raped before being killed.
This is an unpleasant film about a disturbed Vietnam vet and his buddy and the whole movie is steeped in oppression - you'll want to take a valium and a shower after watching this.
That said, it's a shame it's not out on video or DVD as I wouldn't mind seeing it again to see if its quite the same film as I recall and also to see Linda Hamilton in her first ever movie role!
