This is a traumatic film. But is offers a way to deal with it. Most of us (it was my case), when we went to see it, we were prepared for a horrible scene, much talked about. It's much more than that scene. Though it is central. The narrative is told in a incredible way. Going back in time, what we think about the characters, changes once again and again. And the trauma, we face it, and go back to when there was none.
