After weeks of trying to find a good film on Netflix (having watched almost all the decent ones) I finally came across this gem. A hugely enjoyable Spanish psychological thriller that I was glued to throughout - and a few unexpected plot twists along the way. Really enjoyable movie (there are actually a few really good Spanish thrillers on Netflix if you take the time to find them). Disturbing, creepy, suspenseful, good acting, good camera work and a fantastic ending. At times disturbing to watch, but that's why we enjoy psychological thrillers, isn't it? I give it 8 out of 10.
