I'd heard of the film title - assuming the apparently cult classic of '79 - but never seen it -
l I saw this on bluray on Play for a reasonable price and decent star rating so bought it.
I do have a fair collection of horror movies, but none touched the nerves like this one did!
I have literally just finished watching it, on my own, late at night. There were points where I wasn't only cringing, but I was curled up, talking to myself, with the hood on my hoodie up on my head, only just managing to keep looking at the screen.
The attack on Jennifer is just pure sick and probably shouldn't be legal to include in movies ... however the revenge she brings on the men later is also very sick and I guess should follow the same logic ... but I found myself wanting her to get her revenge.
This film is as described, brutally graphic, and very sick. The last film to come close to having this effect on me was Eden Lake ... but it was a long shot from this!
