There comes the scene when Jackie must confront her children, and explain what has happened to their father. The cinematography, score, and acting in that scene is unforgettable. From that moment you will be mesmerized. What an incredible performance by Portman, completely awe-inspiring.
The most emotional film I've ever seen. This film simply brings about the entire array of human emotions one can feel and amplifies them. A triumphant rumination of the human condition rendered in a universal language.
