This movie was worth watching if you don't like to have to story line of movies "spoonfed" to you. Molly's loss of her husband had made her unpredictable and miserable, and I can relate to her fear and depression. It was probably the most realistic portrayal of someone who has lost a loved one that I have seen in a long time, and her actions, although irrational, made the viewers understand how desperate she was to be in the presence of her dead husband. I believe the reason that she did those crazy things that she did was so she would feel Joel's presence around her.
She wasn't interested in moving on in a relationship with someone else, she was putting all her energy into making everyone in her life think she was over her husband's death.
I thought this movie was very thought provoking and made me realize how fragile the human mind is, and how people deal with loss and grieving.
