“Do you like Kierkegaard?” As flirtatious chit-chat goes, this one sets 17-year-old Heather (Brittany Nicole Williams) apart. You can also see why the jock she’s asking (Carlos Alcala) just walks away. Sadly, this is par for the course for Heather, a pescatarian brainiac who is ostracized by classmates at her Ohio high school for being a “freak,” and quietly stifled at home by a loving but clueless widowed mother (Lauren Elder).
How our heroine suddenly gains popularity is at the heart of “The Gospel According to Heather,” a musical by Paul Gordon (“Jane Eyre,” the Off Broadway success “Daddy Long Legs”) that recently opened at Theater 555 in an Amas Musical Theater production directed and choreographed by Rachel Klein (“Red Roses, Green Gold”).
The title gives an inkling as to what suddenly improves Heather’s standing: She is revealed as a Messenger, with the disciples and the powers that go with the role. As it turns out, understanding 19th-century Danish philosophers is not the only miracle Heather is capable of. She can also heal the severely injured and bring the occasional hamster back to life. The presence in the cast of Katey Sagal (“The Conners,” “Sons of Anarchy”), the veteran TV actress, almost qualifies as another of those unaccountable surprises.
Sagal plays Agatha, a sarcastic, wheelchair-bound woman whom Heather likes to visit at a senior center. Sagal makes the most of a handful of lines, and then becomes the center of a major 11th-hour twist.
Heather’s elevated status leads to new headaches, and she can’t decide if she wants to be an anonymous normie or if the change might have rewarding aspects — the show uneasily tries to navigate satire (of conservative fearmongers), whimsy (those crazy teens!) and spirituality (there is more to the show than a Messenger).
What is certain is that Heather is attracting attention from friends and foes alike. The populist podcast host Booker (Jeremy Kushnier) definitely belongs to the foes camp, but it’s unclear at first where the strapping Zach (Carson Stewart) lands.
It was probably not a great idea for Gordon to name his main character in a way that triggers memories of the cult movie “Heathers” and its extremely fun musical adaptation from 2014 — especially since like this show, they center on a bright, alienated Ohio girl who falls for a mysterious boy who tends to enter her bedroom through the window. This is not a comparison this show should encourage.
The book lacks coherence, but Gordon’s score is frustrating for a different reason: It actually has potential. The production kicks off brightly with “My Name Is Heather Krebs,” a jaunty tune with a couple of solid melodic hooks that suggests there might be more nuggets to come; alas, too many of the numbers sound tacked on or unfinished. If only a teenage Midwestern messiah could come to the rescue.
