This has to be one of the best horror movies ever! Toni Collette gives a performance of a lifetime and I think possibly the best of her career. Just when you think you know what's going on, the movie flips. It's so amazingly written and such a thrill ride. Not for the faint of heart!! I've watched this so many times but still get the same chill every single time. Definitely would recommend to horror fans! Review: 10/10
