Just got back from seeing the last house on the left...and what can I say, Damn horrific!! 
The group of mates I went with wernt prepared for it at all! and neither was anyone else in the audience by the reaction of everyone!
A group of people behind us got up during 1 scene, stating loudly "im not sitting through this" and all left...and some more people nearer the front left too, i have never seen someone walk out of a cinema before.
And to top this off a women a couple of rows down, started having what seemed like a panic attack, the guy she was with was attempting to calm her down, before eventually leaving.
Certainly a horrendous film, some horrible bits in it.
