‘Maybe Happy Ending’ Review: Darren Criss and Helen J Shen Are Robots in Love

Claire is low on energy, so she pops across the hall to Oliver’s pad for a pick-me-up. But Oliver, a creature of routine, doesn’t like being interrupted while listening to jazz and waiting for mail. She insists, he gives in, and a spark, maybe a literal one, is ignited.

Never was a meet cute as cute — and as quietly ominous — as it is in the musical “Maybe Happy Ending,” which opened Tuesday at the Belasco Theater. That’s because the pair are robots, and Claire’s battery is running down fast. Hooking her up to his charger may signal, for Oliver, the beginning of love. It may also signal the end of it.

That we nonrobots also connect, pair and empower one another to share a too-brief lifetime is the surprising double vision that makes “Maybe Happy Ending” a ravishing addition to the catalog of Broadway nerdicals. The term is high praise, honoring supersmart, usually small-scale shows — like “Fun Home,” “The Band’s Visit” and “Kimberly Akimbo” — that nevertheless have big emotional impact. This one, directed with breathtaking bravura by Michael Arden, gets bonus points for difficulty, too: Under cover of sci-fi whimsy, it sneaks in a totally original human heartbreaker.

The sci-fi elements are handled lightly and humorously in the book by Hue Park and Will Aronson, thus dodging the invidious scrutiny that the genre often elicits. By 2064, when their story takes place, Helperbots — android servants like embodied Siris — have been assisting humans with daily tasks for decades. But Oliver (Darren Criss) and Claire (Helen J Shen) are now obsolete, living out their days in a pleasant retirement home in Seoul as their operating systems antiquate and replacement parts become scarce.

Still, they remain fully sentient and distinct. Oliver, an early model Helperbot 3, is more stylized and herky-jerky than Claire, a later model Helperbot 5. His lips are pursed, his feet splayed, his language not quite natural (he can’t stop saying “thank you”) and his hair a hard helmet like a Playmobil figurine’s. Even so, he spent enough years with his former owner, James Choi, to have absorbed some human analog tastes — the jazz LPs especially — and to miss him fiercely. Surely Choi (Marcus Choi, excellent) will reclaim him one day.
