Dogtooth (2009)

One of the most cerebral, and entirely unpleasant films ever made, but there were certain moments of the film that left me in awe. The acting is frighteningly good. It's a believable portrayal of a brainwashed family. I squirmed every time a character was beaten by the father or beaten themselves. It portrays a horrifying existence absolutely breathtakingly. You either love this movie, or you hate it. I'm pleased to find myself on the love side.
