When You Finish Saving the World, Jesse Eisenberg’s directorial debut and based on his own novel, stars Julianne Moore and Finn Wolfhard as a mother and son with serious social and communication issues, both with each other and the rest of the world. This is an insightful, sometimes funny, sometimes cringeworthy depiction of a conflict between two generational stereotypes: self-satisfied, affluent liberal Boomers and self-absorbed Gen-Zers who are more comfortable interacting online than in person. To its credit, the film doesn’t really take a side as both generations are lampooned.

Julianne Moore plays Evelyn, the director of a woman’s shelter in Indiana. Her teenage son, Ziggy, spends all his free time live streaming a music program that is broadcast globally to, he can’t stop announcing to everyone, 20,000 fans. Jay O. Sanders takes a back seat as Ziggy’s father, whose low key presence mainly consists of drinking wine, retreating with a book to his bedroom, and avoiding conflict as much as possible.

Ziggy is the kind of part Eisenberg himself would have played 20 or so years ago. In fact, this film vaguely evokes a 90s film in which he appeared, The Squid and the Whale, as both depict highly dysfunctional upper middle class families. Wolfhard is very effective in this role as a character who is often less than sympathetic. He’s both awkward and self-centered, oblivious of how off-putting his behavior often is.

Despite his apparent popularity online, Ziggy is socially awkward with his peers. He becomes infatuated with Lila (Alisha Boe), a politically active classmate who reads poetry at a local radical community center. Ziggy makes some ill-planned attempts to impress her. He turns one of her poems about oppressed people into a song and then brags how much money he made online with it. Ziggy suffers from the delusion that social media posturing is the equivalent of making a real difference in the world.

Evelyn is equally uncomfortable to watch. One of Julianne Moore’s strengths is playing characters who try to put on a brave front while barely hanging on emotionally. We saw this recently in May December, where she plays a woman living in the aftermath of a scandal. Here, she is equally off balance at home with Ziggy and her uncommunicative husband and at work, where she awkwardly tries to balance her role as supervisor with her egalitarian values. In one scene, her efforts to get friendly with a receptionist results in the other woman asking if Evelyn is planning to fire her.

Evelyn becomes obsessed with Kyle (Billy Bryk), a teen who goes to school with Ziggy (though the two are not acquainted) who is staying at the shelter with his mother. At first, she appears to take a maternal interest in Kyle, who seems more grounded and easier to communicate with than her own son. However, it starts to go in a queasier direction when she takes him out to dinner and gets giggly and flirty with him.

We need to look beyond Ziggy and his parents to find characters who are relatively normal and well adjusted. We see their foibles through the eyes of Lila and Kyle. The film’s major weakness is probably that the nearly perfect symmetry between Ziggy and Evelyn’s awkward interactions stretches credibility.

What I liked best about the film were some of the casual and offhanded observations. For example, we see Evelyn and Ziggy squeezing into an ostentatiously tiny Smart car, which is parked in one of the neighborhood’s larger and more ornate homes. This perfectly captures Evelyn’s need to be seen as a socially conscious activist while living a comfortable life in an upscale suburb. Then there’s the everyday hostility between Ziggy and his parents, who casually hurl obscenities at one another. This might be shocking to anyone not familiar with the norms of many liberal middle class families. Ziggy is especially territorial about no one disturbing him while he’s vlogging.

When You Finish Saving the World reveals how difficult communication can be in the modern world. . But overall, Eisenberg and the actors do an admirable job of sending up people whose self-importance and grandiosity can overshadow good intentions.
