On 12 acres of property in Idaho on the top of the ridge, the sky is so intense it makes Ethan (Micah Stock) panicky because he feels that his life is insignificant against the vastness of the galaxy glittering before him. Sarah (Laurie Metcalf), Ethan’s aunt who owns the property and appreciates the nighttime view tells him she “thought once about buying a telescope, but you know. Then I’d own a telescope.” The audience laughter responding to Metcalf’s pointed, identifying statement that reveals her edgy, funny character peppers Samuel D. Hunter’s powerful, sardonic Little Bear Ridge Road currently at the Booth Theatre.

Metcalf is terrific as Sarah who delivers comments like darts hitting the bullseye and evoking laughter because her words are heavy with authenticity. Her statements convey meaning and pointedly eschew the gentility of polite conversation. Micah, Sarah’s nephew, is withdrawn, remote and masked, not only because the play begins during the COVID-19 pandemic, but because he wears his soul damage on the exterior with a covering of silence that withholds speech. Interestingly, these two estranged family members, one a nurse who doesn’t even nurture her own wounds, and the other, a self-damaged young man of thirty, who can’t really get out of his own way, eventually get along,

With this Broadway debut Hunter (The Whale, A Bright New Boise) weaves a poignant, humorous, fascinating dynamic. Metcalf and Stock inhabit these individuals with humanity and a fullness of life that is breathtaking.

Directed crisply with excellent pace and verve by Joe Mantello, Hunter’s comedic drama that premiered at Steppenwolf Theater Company, confronts human isolation and failed familial relationships. Hunter presents individuals who confuse self-supporting independence with misguided self-reliance. With spare, concise dialogue the playwright explores how Metcalf’s Sarah and Stock’s Ethan rekindle their sensitivity and open up while nursing their fractured, self-victimized souls, to help each other without acknowledging it as help.

Finally, Hunter’s dialogue has flourishes of well-placed poetic grace and rhythm. Within its meta-themes about human beings struggles with themselves, it’s also about knowing when to let go to encourage another’s growth.

Aunt Sarah and nephew Ethan have an ersatz reunion, when Ethan’s father, Sarah’s brother, dies and leaves the nearby house and estate to Ethan to dispose of. Estranged from his father and from her for a number of years, Ethan, who is gay, lived in Seattle with a partner, who emotionally abused him and self-medicated with a cocaine habit. Eventually, they split. Graduating from university with an M.F.A. in writing, Ethan has drifted, stunned by his devastating childhood where he was raised by an addict father, since Ethan’s mother abandoned the family when he was little. How does Ethan learn not to duplicate his problematic relationship with his father, with love relationships with other older men?

For her part Sarah remained in Idaho near where she was born and worked as a nurse during and after her husband left her. Fortunately or unfortunately, they had no children. This means that she and Ethan are the only Fernsbys left on the planet, dooming their family line to extinction, which according to Ethan seems pathetic. Selling her home in Moscow, Sarah tells Ethan she moved to a more remote area because “It suits me better. Not being around—people.”

With her prickly, self-reliance and proud stance refusing help, Sarah has taken care of her house and property, worked, organized documents and paperwork for Leon (Ethan’s dad, her brother). She generously gave Leon money to help him with his bills. When Ethan affirms that was a bad idea because his addict father used it for his meth habit, Sarah states she doesn’t know what he used it for. After all, Leon told her that he never did meth in front of Ethan. The truth lies elsewhere.

As the pandemic passes and circumstances improve, the relationship between aunt and nephew also improves. They communicate more intimately. They watch a TV series and comment about the characters. The dialogue is funny and Sarah and Ethan become family. Assumptions and mistaken views are dismissed and overturned. Realistic expectations fill in the gaps. A surprise occurs when Ethan meets and forms an attachment with James (the excellent John Drea).

Hunter uses James as a catalyst, who provokes a turning point to continue the forward momentum of the play. James comes from a more privileged, loving background and is studying at a nearby university to be a star-gazer for real, an astrophysicist. With eloquence James explains the magnificence of Orion’s Belt to Ethan, as it relates to our sun. Sarah welcomes him and encourages his relationship with Ethan, until once more circumstances gyrate in another direction, all perfectly unfolding with the emotion of the characters.

Mantello arranges the interlocking dynamic among Sarah, Ethan and then James, center stage on a “couch in a void.” From there the characters converse, sit, enter and leave stage right (to an invisible kitchen), stage left (to bedrooms). The recliner couch on a turntable platform in different positions establishes the passage of time between 2020 and 2022. Scott Pask’s set and the lighting by Heather Gilbert are symbolic and interpretive. Our focus becomes the characters and the actors’ exceptional portrayals as they struggle to find a home with each other and themselves, until the threads of grace in their alignment come to a necessary end.

After all, the Fernsbys have to have a legacy, if not in offspring, then in words. And the respite and connections they find together talking and watching TV on a “couch in void” becomes the place where Ethan’s legacy in writing is born, and the Fernbys legacy prevails.

Little Bear Ridge Road runs 1 hour 35 minutes with no intermission at the Booth Theater through February 15th littlebearridgeroad.com.
