A man goes down on his wife. When he comes up for air, we learn her vaginal smell portends motherhood. Yes, the cunnilinguist (played by the very placid John Krasinski) knows something more about vaginal odors than the average joe. The problem with the movie isn’t the joke itself, it’s the maudlin, agonizingly stretched-out life lessons that follow — as if the husband-wife scriptwriters, Dave Eggers and Vendela Vida, made a deal: “Okay, Dave, I’ll go along with your raunchy idea for an opening, but we’re going to redeem it by following it up with two hours of earnest, sentimental, family-values rich material.”

“Away we go!” was much better as a Jackie Gleason catchphrase.
