NEW YORK — At first glance, “Maybe Happy Ending” seems like a strange concept.

This new ambitious musical, which debuted on November 12 at the Belasco Theatre, tells the story of two lonely robots on a road trip, experiencing love in a futuristic version of South Korea. This narrative feels reminiscent of if Rosey from “The Jetsons” found herself in a whimsical Nora Ephron romantic comedy, blended with elements from “La La Land” and a touch of Charlie Kaufman.

Yet, surprisingly, these varied components come together brilliantly, creating a fresh and emotionally powerful experience, largely due to outstanding lead performances and the exceptional direction of Tony Award winner Michael Arden (known for last year’s “Parade”).

The story kicks off with Oliver (Darren Criss), a detail-oriented android waiting for his owner, James (Marcus Choi), to pick him up from a rundown high-rise filled with outdated robots. Content with his houseplant and extensive jazz collection, his life changes when a spirited “helperbot” named Claire (Helen J. Shen) knocks on his door, desperately needing help with her malfunctioning charger.

Their initial interactions have a charming comedic rhythm as they navigate their budding emotions. As their playful arguments evolve, we learn more about them: Claire dreams of seeing fireflies light up the sky, while Oliver is on a heartfelt quest to find James, who disappeared years ago without a word.

<pTogether, these unlikely companions embark on their journey. Criss shines in his portrayal of Oliver, displaying an engaging personality that, despite the cheerful exterior, grapples with the harsh truths of existence. While portraying a naïve character, Criss strikes a wonderful balance, effectively delivering many of the show’s comedic moments, including a clever scene where Oliver short-circuits after nervously drinking a cocktail.

Shen excels in her Broadway debut, portraying Claire with a captivating mix of humor and vulnerability as she faces the reality of her fleeting existence. Her stunning vocals fit perfectly with the beautiful score by Will Aronson and Hue Park, which stands out as one of the best to hit Broadway in years. Dez Duron’s rich singing also impresses as he plays a soulful jazz singer who Oliver admires.

While the show has a few minor flaws, such as a slight pacing issue in the final act and some predictable dramatic twists involving Oliver and Claire’s previous owners, these shortcomings are easily overlooked given the overwhelming positives of Arden’s captivating production. The show is surprisingly lavish for what is, at its core, an intimate two-character musical.

The vibrant costumes designed by Clint Ramos and the artful lighting by Ben Stanton create a visual delight, while Dane Laffrey’s impressive set design transforms the stage into varied locations—from a shabby motel to a lush field filled with fireflies. The clever use of projections by George Reeves enriches the storytelling, pulling the audience into Claire and Oliver’s shared memories.

“Maybe Happy Ending” stands as perhaps the most innovative musical on Broadway since 2022’s “Kimberly Akimbo,” which also explores profound themes within a compact narrative. With its blend of gentle humor and poignant themes, Park and Aronson provoke the timeless question: Is it worthwhile to love, knowing sorrow and loss are part of the equation?

This show is crafted to touch the heart and evoke tears. Judging by the heartfelt responses from the audience, it’s evident that this rare and tender musical resonates genuinely.
