Surprising movie in a good way. A story really well elaborated and more, still well executed. Performances from all the cast really good but definitely the stronger is Rebecca de Mornay'. Always with the same nuts face along with a excellent performance. Rebecca's performance was crazily good, she mixed the sadistic with calmness in a excellent form. One thing I liked, beside the characters aren't mentions for intelligence, they weren't the typical dumb teenagers, were adult people afraid and acting on under pressure and control. I found that really nice. It left the movie with a serious tone. Another thing, it has no jokes at crucial moments, it was taken very seriously, it also counted a lot. If you like violent thrillers, plus plenty of blood and tension, this will appeal you in full. A pity that it hasn't gone to the cinema, certainly deserved a chance.
