There are three reasons I think you should see this film:
1. Crying is good for the soul, and the healing process. And you will cry. You might be like me, and just tear up while you watch, and then as soon as it's over - the flood gates open. The song playing during the disc menu doesn't help...
2. The movie addresses complex grief issues that people don't often understand - like how we blame ourselves for our loss, that grief can take on various forms such as anger, how loss brings up underlying emotional scars, how loss effects different people in different ways, and how the loss of a child effects all your relationships.
3. I love Natalie Portman.
