Disturbing distasteful ruined my night
18 October 2015 | by See all my reviews

Words cannot describe how much I hated this movie. The sick twisted person who wrote this screenplay should be held for observation. I am normally a happy fun loving guy but this movie ruined my evening and I crashed at 10:30 on a weekend night.

Since I need to write 10 lines to meet the minimum requirements so I can warn other potential viewers about this movie, I will give a few sentence synopsis. Two young girls break in on a nice guy at his home one stormy evening. They assault and brutally torture him over a couple of days. Nothing sexy or funny or intriguing. Just brutal torture and murder.
