Right away I’m thinking that this Paul Weitz film is way too in love with the idea that feeling or showing awkwardness is funny. That it has far too much faith in coy quirk. That “a quick-witted, slightly older woman is suddenly confronted with motherhood” is not, for me, an intriguing premise. That the trailer is giving every impression that the film, which costars Tina Fey and Paul Rudd, is a second-tier sitcom.
