These words/feelings came into my mind after the end of the movie: confusing, unsatisfying, violent and too long.
I think this movie was not realy for me, it's a lot like Fargo(which I also didn't like).
It's okay if a movie let's you think about the ending, but in this case it was just too much.
Was it a bad movie? No! There was suspense, I liked the direction and camera angels and the actors did show an awsome performance. But is it realy Oscar-worthy? In my oppinion not.
