Ten minutes with Toni Collette's Beth and you'll understand why her husband (Greg Kinnear) wants to be rid of her. As an adult drama, Dinner With Friends is apt enough at exploring late-thirtysomething angst and crisis, well acting and paced with enough momentum to keep the story from dragging. Too bad the emotion is all on the surface, making it difficult to identify with any of the characters in a positive way.
