With his rapid-fire delivery and big heart, Rockwell makes Owen his version of “M*A*S*H”’s Hawkeye Pierce, but the film’s layers of well-observed truths go deeper than that.

Faxon and Rush’s screenplay doesn’t deviate too far from formula, but their sturdy direction, bolstered by handsome production values, evokes a wistful sense of carefree summers and conjures up a potent amount of simmering teenage angst beneath the frequent chuckles.

Comedy is hard all on its own, but comedy that resonates is a rare thing indeed. So it’s admirable that Rash and Faxon are continuing to head down that path they started with “The Descendants,” even if this film isn’t quite as refined.

There's something slightly formulaic and familiar about Nat Faxon and Jim Rash's coming-of-age film The Way, Way Back, but not enough to dampen its crowd-pleasing charm.

The performances and the ready supply of one-liners make this an amusing look at a new generation getting lost down memory lane.
