Tommy Lee Jones, Meryl Streep, and Steve Carell (in a delightfully different role) make up the main characters in this movie. It's entertaining to watch and extremely well acted by all three.
Streep is frustrated by her disinterested, slightly jerky, husband Tommy Lee Jones, who, after 30 years has settled into about the most boring routine of married life. They haven't shared a bed for many years; sex is non-existent; she has nothing interesting to say to him---and he's not interested even if she does. His job is boring; at home he buries himself in the newspaper and watching golf on TV. He prefers to eat alone and never touches his wife or speaks more than two words, and then goes to bed. Repeat, day after day, after day.
Streep in frustration sets up an intense week long marriage counseling vacation in Maine. Steve Carell is the therapist. It's painfully awkward to watch this couple grapple with their issues, but it doesn't drag the viewer down. All of these people are SO good and believable in their roles, capturing every little mannerism and nuance of their characters, it's as though you're hiding around the corner watching and listening in on their meeting. It's a quiet film, which won't appeal to the adrenaline junkies, but it is a fascinating character study of a long-time married couple who have long ago lost the spark that drew them together.
It is the story of how a once thriving marriage loses its way through the years without realizing it. It's not overly serious, but serious nonetheless.It has a few endearing moments, but not ever sappy. It doesn't take sides, though at first it seems like all the problems are his. By the end we realize it takes two to make a happy marriage and most (not all) it takes two to ultimately destroy it. The ending is as it should be. Interesting to see Steve Carrell in a role that wasn't laugh-out-loud funny.
