Private Life: as far as sharing the goals of the main characters in Tamara Jenkins’ dramedy goes, your mileage may vary; but that goal is very easy to grasp, therefore the story is emotionally touching every step of the way. The story also opens up the beyond the central pair, and treats all threads in very humane, believable ways. Kathryn Hahn and Paul Giamatti are both spectacular: emotionally raw, vulnerable, very credible, and managing to find a lighter, sweet-and-sour tone very often. Kayli Carter is overmatched, playing her air-head character a bit too broadly (particularly in light of their subtleness). Well shot by cinematographer Christos Voudouris, who does enough to avoid a samey, overly common look without calling attention to itself.
