Qui Nguyen’s crowd-tickling comedy about a Vietnamese family in Arkansas mixes hip-hop and martial arts with soapy twists and turns.The playwright Qui Nguyen has made a career of imagining marginalized people as heroic leads. That includes his parents, who emigrated from Vietnam and met in an Arkansas refugee camp, a story Nguyen chronicled in his raunchy rom-com-style play “Vietgone.”“Poor Yella Rednecks,” which opened Wednesday in a rollicking, comic book-inspired production at New York City Center, picks up five years later, in 1980, when their marriage hits the rocks and the playwright is a 5-year-old struggling to learn English.Commissioned by Manhattan Theater Club and South Coast Repertory, where it premiered in 2019, “Poor Yella Rednecks” functions as the playwright’s own superhero origin story: Nguyen has become not only a wizard of language and form, but also an expert M.C., subverting and remixing conventions to confront abiding questions about displacement and assimilation. How can immigrants become legible to the American-born generations of their own families, and to audiences who are so white, the playwright’s mother says, that they resemble a Fleetwood Mac concert?Nguyen’s answer is an expletive-filled fusion of hip-hop and martial arts with the soapy twists and turns of addictive serial television. Under the wry and nimble direction of May Adrales, “Poor Yella Rednecks” is a crowd-tickling comedy that squashes preconceptions in order to place hearts in a vise grip.Framed as recollections Nguyen gathered from his mother, Tong, in 2015, the show begins with the playwright (portrayed onstage as a middle-aged man by Jon Norman Schneider) interviewing Tong (a dynamite Maureen Sebastian), who speaks with a pinched face and a thick accent. But Tong soon demands to have her son’s “pot and a mouth” style of talking in the play he is writing, and for white characters to sound the way she hears them, as a garble of slang and empty signifiers (so he has them squawk exclamations like “Yeehaw!” or “Mitch McConnell!”). From then on, we hear Nguyen’s family talk in frank, and often crass, English when they are understood to be speaking Vietnamese. (Nguyen’s parents were heartbroken when they met, Tong says, “so we comforted each other with our crotches.”)Though his family’s history is rooted in upheaval and loss, Qui Nguyen presents it with a delicate balance of over-the-top humor and unforced sincerity, our critic writes.Richard Termine for The New York TimesRewind 35 years, and Tong tears away her granny garb (thrifty southwestern costumes designed by Valérie Thérèse Bart) to play a younger version of herself. Tong and the playwright’s father, Quang (Ben Levin), who looks like a matinee idol but can’t find work, are nearly broke and are each being drawn back into previous relationships. Tong, a waitress at a diner, partly blames her mother, Huong (a dry-as-gin Samantha Quan), for the difficulty that her son, known as Little Man and represented by a wide-eyed puppet, faces fitting in at school. Huong, who only speaks Vietnamese, worries that learning to talk like his peers will turn Little Man (endearingly designed by David Valentine and maneuvered by Schneider) into a stranger.As in “Vietgone,” “Poor Yella Rednecks” shows Nguyen’s onstage parents expressing their most vehement feelings, and occasional exposition, in verse, rapping over uncomplicated beats composed here by Shane Rettig, who also designed the game show-like sound. (“Cuz I’m more than just pretty, my brain is damn witty,” Tong raps. “Gimme one hot second Imma run this city.”) For the title song, Nguyen borrows a familiar declaration about the work ethic of immigrants from the musical “Hamilton,” though his own less sophisticated lyrics, which are better at illuminating conflict than romance, may not exactly hold up in comparison.Though rooted in upheaval and tragic loss, Nguyen’s family history is presented with a delicate balance of over-the-top humor and unforced sincerity. Jon Hoche, who plays Quang’s best friend Nhan, is a boisterous bro with a soft underbelly, while Paco Tolson is almost pitifully hapless as Bobby, Tong’s bumbling white ex. Tolson also plays the godfather of Marvel, Stan Lee, whose presence as a sporadic narrator adds to the show’s graphic-novel aesthetic; the set by Tim Mackabee spells out “yella” in big, rotating letters, lit in emphatic color by Lap Chi Chu.For all of its surprises, including action sequences I won’t spoil here, the play falters only when it tips into obviously earnest territory. Nguyen doesn’t need a surrogate to detail his intent; the story soars on its own.Poor Yella RednecksThrough Nov. 26 at New York City Center Stage I, Manhattan; manhattantheatreclub.com.
