The remarkably consistent Noah Baumbach returns with While We’re Young, a sharply well-observed and thoughtful comedy filled to the brim with life-affirming wit and wisdom. It feels like his most empathetic and personal film to date, which draws on the themes of adulthood and nostalgia with a sort of infectious vigor that kept me charmed the entire time. While its depiction of generational division is inherently timeless, the movie also has an uncanny sense of time and place that constantly keeps things relevant and relatable to adults of any age.

The story centers around middle-aged couple Josh (Ben Stiller) and Cornelia (Naomi Watts), who feel increasingly alienated from friends who insist that having a baby will change their lives for the better. Fortunately, their social anxieties about aging and impending irrelevance begin to subside when they strike up a friendship with hipster (yes, I said it) twentysomething couple Jamie (Adam Driver) and Darby (Amanda Seyfried). Their carefree attitude and effortless zeal begin to rub off on Josh and Cornelia, until Jamie’s work on a new documentary feature begins to call the motives of the young couple into question.

Authenticity then becomes a more prevalent theme throughout the film, as Josh and Cornelia begin to strip away the layers of ironic detachment that cover their new young friends. There’s an element of presentation with Jamie and Darby that is immediately attractive to the older couple; Josh borrows an affinity for pork pie hats while Cornelia even attends a hip-hop dance class with Darby. But the question always lingers: how much of this is a show? What are Jamie and Darby getting out of this? The movie does a very good job of providing open-ended answers to those questions, leaving us with enough to go on but also enough to speculate on their true nature.

Of all of the film’s brilliant cross-generational examinations, the most rewarding is its depiction of the relationship that the two groups have with technology. Most movies would take the easy route, having the youngsters doing technological laps around the old folks for laughs, but it’s the twentysomethings here that have a more old-fashioned way of living. A mid-way montage highlights this juxtaposition beautifully, cutting together shots of Ben and Cornelia clutching their iPhones and Kindles with Jamie and Darby loading up a VHS copy of The Howling or selecting from a vast collection of vinyl records. Cornelia even remarks “It’s like their apartment is filled with things we once threw out, but it looks so good the way they have it!”

That quote also implies a type of bittersweet resentment that almost seems inevitable as one ages. No matter how old you are, there is always someone younger that you can choose to begrudge. What While We’re Young demonstrates in its closing line is a type of acceptance of this, followed by a final moment of levity that nicely ties all of the film’s themes together. Whether you’re old, not yet old or somewhere in between, this movie is well worthy of your time.
