Grief combines with melancholy humor and exceptional performances by the leads in Mitchell's family drama, an expanded version of Lindsay-Abaire's prize-winning play that the writer adapted for the screen. Since the accidental death of their four-year-old son Danny, Howie (Eckhart) and Becca (Kidman) find themselves coping in very different ways. Becca wants to sell the house and move on but Howie can't bear changing anything relating to their son. They try group grief therapy but angry Becca can't abide the sharing while Howie finds it cathartic. Since both turn away from each other, the marriage may also not survive.
