When did you first see this? Where were you? What did you think?
This was the first "R" rated movie I watched on the (then NEW) cable TV in about 1978 . I enjoyed it and I enjoyed it's "R Rated-ness". LOL . I was in high school at the time and at a friend's house.
But today:
This movie suffers from too much police procedural and too too much borrowing from "Rosemary's Baby".
I also remember walking by a local movie theater in 1977 and this was playing. I had no idea it was a horror movie !
I thought it was about a security guard protecting a rich woman from someone that was out to get her. LOL.
