Sunny Sandler’s Breakout Turns ‘Don’t Say Good Luck’ into a Standout Netflix Musical Drama

Verdict: A Familiar Story, Elevated by a Remarkable Lead

Don’t Say Good Luck is a Netflix musical drama about a high school student chasing the lead in a stage production while her family quietly buckles under the return of her mother’s cancer, mixing performance, grief, and adolescence into a bittersweet coming-of-age story. From the first scenes, this is less a glossy teen fantasy and more a slow-building emotional fuse. At its core is Sunny Sandler’s performance as Sophie Birenbaum, whose mix of gawky teenage insecurity and on-stage assurance carries the film’s heaviest moments. Opposite her, Melanie Lynskey brings a soft, exhausted steadiness as Elizabeth, the mother whose illness shapes every choice the family makes. The result is not a radical reinvention of the genre, but a thoughtfully made tearjerker that will land hardest with viewers who appreciate musical storytelling and are willing to sit with a story where the emotional payoff arrives late rather than loud.

Sunny Sandler’s Emotional Breakout

Sophie’s arc looks straightforward on paper: an ambitious sophomore dares to audition for a part in her school’s staging of the Broadway hit Waitress, only to land the lead instead. What turns that outline into something affecting is the Sunny Sandler performance at the center. She is believably small and awkward in the hallways, then startlingly composed when the lights hit and the music starts. Her live rendition of “She Used To Be Mine” plays twice—once on the school stage in front of her family, once in a more intimate backyard setting—and both sequences are framed as emotional peak points, not talent-show flexes. Those performances become the film’s spine: each lyric doubles as confession, each note a pressure valve for feelings Sophie refuses to voice at home. It is an emotional breakout role that marries singing, acting, and a quietly specific sense of teenage overwhelm.

Away from the spotlight, Sophie’s life intentionally borders on mundane: minor boy drama, a best friend dispute, one messy night of underage drinking, the usual grind of rehearsals and homework. On their own, these scenes can feel slight, even basic, especially in the first half. Yet by keeping her non-family problems grounded, the film sets up a jarring contrast when her two worlds collide near opening night. The day-to-day teen fodder you might tune out at first becomes the context that makes her late-film choices sting. When Sophie finally has to decide whether to cling to the show or stay with her fading mother, all those earlier trivialities fold into a portrait of a girl who was allowed to be ordinary until life stopped being ordinary at all.

A Bittersweet Musical Tone with Strong Supporting Chemistry

What sets Don’t Say Good Luck Netflix apart from many school-set dramas is how it threads musical set pieces into a story about illness without sliding into melodrama. Director Julia Hart uses the Waitress numbers less as flashy detours and more as emotional mirrors; the show-within-a-show becomes a safe place where Sophie can say the things she cannot bring herself to tell her family. Surrounding her is an ensemble built from comedy ringers: Jon Lovitz as a cranky drama teacher with opinions about kale wraps and Annie, Steve Buscemi as a grandfather warning about “handsy” boys, and Max Greenfield wrangling his own unruly sons, all adding sharp, light touches. These beats never fully turn the film into a comedy, but they keep the tone from collapsing under its own heaviness, making the sadder scenes feel earned rather than relentless.

The emotional core, though, belongs to the relationship between Sophie and her mother Elizabeth. Lynskey plays Elizabeth as someone fighting to stay both alive and upbeat, bantering about hot chauffeurs and silly accents even as her energy drains. The script keeps mother and daughter on parallel tracks, each trying to protect the other from the worst truths about the cancer’s progression. That push-and-pull—Elizabeth insisting Sophie live her “best teenage life,” Sophie craving the full picture so she can decide how to spend their remaining time—creates a low, constant tension. Their private scenes act like emotional check-ins for the audience: small, warm, sometimes awkward, often funny. According to one early review, these interactions “elevate the story above a more standard coming-of-age high school experience or family drama.” By the final act, their mutual admission that neither knows the right way to move forward delivers the film’s most affecting moments.

Trade-Offs: Slow-Burn Drama, Big Payoff

As a Netflix musical drama, Don’t Say Good Luck makes some deliberate trade-offs that will either win you over or lose you early. The pacing favors slow fades and domestic detail over twisty plot; much of the film is spent watching Sophie juggle rehearsal notes, soft crushes, and half-heard medical updates. The teenage subplots, while credible, lack surprise and risk feeling routine if you are more interested in the medical storyline. On the other hand, that restraint is exactly what makes the final act hit so hard: when the musical performances and home-life revelations finally collide, the film stops feeling like two separate tracks and snaps into focus. If you go in expecting a high-concept spectacle, you may be disappointed. If you are open to a modest, character-first story that uses familiar ingredients with care, the payoff is rich.
