Rating: (3 stars)

In “Brittany Runs a Marathon,” Jillian Bell plays the title character, a young woman approaching 30 whose life has stalled into a deadening cycle of partying, meaningless sex, shallow friendships and an off-off-Broadway theater gig that barely keeps her afloat.

As an archetype, Brittany resembles the characters Amy Schumer has played in such makeover comedies as “Trainwreck” and “I Feel Pretty”: the funny, resilient but wounded girl whose
self-deprecation masks deeper self-loathing, and whose self-sabotage veers precariously toward self-harm.

The title of “Brittany Runs a Marathon” is nothing if not literal: Here, the means of the heroine’s salvation is her discovery of running, but the twist is that even that healthy pastime — and the positive changes it engenders — invites new ways for Brittany to indulge her deepest weaknesses.

Written and directed by newcomer Paul Downs Colaizzo, “Brittany Runs a Marathon” is an engaging, modestly amusing, sometimes laugh-out-loud hilarious comedy of manners in which the usual millennial excesses are skewered, from the invidious hellhole of social media to the mendacities of online dating. Photographed in a loose, up-close style, the movie never strays far from the usual advances, reversals and resolutions of similar plots — a familiarity that is either comforting or cliched, depending on the viewer’s frame of mind. To his credit, Colaizzo has enlisted a fine ensemble of actors, especially Michaela Watkins, Utkarsh Ambudkar and a quietly revelatory Micah Stock as Brittany’s newfound posse.

The best part of “Brittany Runs a Marathon” is that it provides a showcase for Bell, who co-starred with Watkins earlier this summer in the terrific indie “Sword of Trust,” and who, before these two movies, has usually been relegated to scene-stealing but all-too-brief supporting roles. Right off the bat, she gives Brittany a quick-witted, improvisatory edge, which eventually is shown to cover up for deep-seated social anxiety. Bell plays all the layers with admirable skill, managing to be tartly funny, abrasively
off-putting and wrenchingly vulnerable within the space of just a few moments.

She also pulls off the physical transformation that forms the somewhat contradictory climax of “Brittany Runs a Marathon.” This is a movie that is adamantly body-positive (“You totally missed the point of those Dove ads,” Brittany complains to a doctor who tells her she’s overweight), but it also revels in the fit, lip-glossed, romantically fulfilled butterfly who emerges from her cocoon of red wine, Adderall and shame.

Not content to leave it there, Colaizzo preempts his foreordained happy ending just long enough to question how Brittany — and the audience — would precisely define that term. “Brittany Runs a Marathon” is perfunctory, idealized, sometimes awkwardly composed, almost always predictable. But it stays the course, with admirable grit and more than a few entertaining grins.
