Talk about an upgrade – Summer Stock Stage presents a Mainstage young artist production of the Broadway hit “Be More Chill.”

Based on a story genre that dates back to tales of Faust in the 1500s, through to modern musicals like “Damn Yankees” and “Little Shop of Horrors,” filtered through the world of teen movies since the 1980s and contemporary youth culture, this musical by Joe Iconis with book by Joe Tracz, based on the 2004 novel by Ned Vizzini, centers on a “Loser Geek Whatever” high schooler named Jeremy (Gabriel Vernon Nunag) whose father (Drew Kempin) is too depressed to wear pants, his crush Christine (Aubrie-Mei Rubel) doesn’t notice him, and his best friend Michael (Alex Pharo) doesn’t mind also being a dork, because he knows they will eventually be “cool in college.”

But Jeremy won’t wait that long. Even risking further unpopularity by signing up for the school play (the Shakespeare-ish “Midsummer Night-Mare with Zombies” adapted by eager drama teacher Mr. Reyes [Luke Aguilar]) doesn’t help because Christine has friend-zoned him – a combination of her ADD and the attention paid by handsome extracurricular-activity hopper Jake (Kendrell Stiff).

In an odd encounter, the school bully Rich (Maddux Morrison) confesses he is mean because he was instructed to be by his Super Quantum Unit Intel Processor, or Squip, which is a black-market Japanese nano-computer in pill form. Once taken with regular Mountain Dew, its circuitry migrates to the brain and gives your personality – and popularity – a total makeover.

At the local shopping mall, Jeremy finds the dealer and buys, then takes, his own Squip (Piper Murphy), which appears only in his field of vision, looking something like a “Tron” version of Timothee Chalamet with greenish hair. This program immediately takes charge of his shopping decisions and when the popular girls show up, has him acknowledge the “beta,” Brooke (Jilayne Kistner), instead of the alpha, Chloe (Jayla Shedeed), to help set up his ascendance in high school society. As for Michael, the Squip employs an optic-nerve blocker so that the BFF is literally out of sight, out of mind.

The cast also includes Isabella Agresta, and Jenna Rolan as the school gossip. Devan Mathias directs, with music direction by Cameron Tragesser and impressive choreography by Darian Wilson.

The set design by Chyna Mayer includes several screens which at times show video linked from smartphones the actors are holding at the time, giving such moments an authentic feel. Costumes by Tony Sirk include the anime-style green Squip cybersuits as well as the odd outfits used in the school play.

Nunag’s performance is excellent, and Rubel’s adorable, while this musical gives the supporting roles plenty of moments to shine, making Kempin’s Mr. Heere and Kistner’s Brooke characters to feel for, as well as lending Morrison’s bad-boy Rich a more nuanced persona. Then there’s the fact that the big hit song is sung by the neglected best friend – as Pharo nails his rendition of “Michael in the Bathroom.”

Murphy, as the Squip, perfects the Terminator stare and affect with cooly-efficient movement. Her aura of subtle menace compels obedience.

While a fun musical centered on teen angst, this tale of the wish to exchange one’s self for a promised “upgrade” harkens back to ancient roots while becoming only more relevant in the current spread of A.I.

After all, we each now hold a compact supercomputer just inches from our brains every day.
