Perhaps the most derivative slasher/psycho film I’ve ever seen. So derivative of Psycho that the bad guy is named “Norman”. And the similarities only begin there.
The one slightly memorable thing about this is villain Toby Wynn-Davies doing a remarkable Burgess Meredith impersonation. So if you’ve ever wanted to see Norman Bates played by an overacting Burgess Meredith in a much worse version of Psycho, this might be the movie for you. Otherwise, skip it.
