A true modern family drama about the inflexibility of divorce and the pliability of intimate relationships, skillfully written, directed and acted. Each of the central characters get multiple chances to show their good guy, monster, and victim personae. And the marriage is treated as a character as well. We see it in danger at the start of the film and then we’re along for the ride as it passes through phases of prognosis ( and painful diagnosis) before it settles into its final comfort.
