udd Apatow’s movie (co-written by star Steve Carell) wants to be a bittersweet tale about escaping loneliness but can’t escape its main-attraction gag. Carell is Andy Stitzer, a video-store supervisor who’s little more than an adult adolescent. He lives alone, collects comic books and vintage action figures, and doesn’t swear. It stands to reason he’s never had sex. Enter zealous cohorts who egg him on, punning and goading and generally making a mess of things. Andy then meets single-mother Trish (Catherine Keener) and the two begin a relationship that excludes … sex. Carell and Keener, efficient and pleasant, do their low-keyed best to keep the story on course, but there’s far too much that’s coarse and obvious. The central insight is that clumsiness doesn’t matter if affection’s in the air. All right then…
