Its almost October, every year my wife and I try and watch as many ****ed up horror movies as we can, some are good most are not. A few I recommend though.
Martyrs- French movie, most messed up movie I have ever seen. Emotionally draining. My wife loved it.
The Loved Ones - Australian, well done, entertaining, I quite enjoyed it.
High Tension - French also, great movie for the first 75% then it ends terribly.
Eden Lake - pretty entertaining more intense than horror but it was worth watching.
I'll update when I find some new good ones.
