Shaina Taub’s new musical at the Public Theater tells the story of the women’s suffrage movement in the years leading up to the passage of the 19th Amendment.I don’t remember my grade school history books dedicating more than a few sentences to the women’s suffrage movement. The nearly 100-year history of women fighting for the right to vote is often trimmed down to two main talking points — Susan B. Anthony and the 19th Amendment — and some dismissed the suffragists as self-serious rabble-rousers.In an effort to counter those notions of these revolutionary women and their fight, the new musical “Suffs” begins with the satirical vaudeville-inspired “Watch Out for the Suffragette!,” sung by the ensemble, made up of female and nonbinary actors. (The show was scheduled to open Wednesday at the Public Theater, but canceled because of positive coronavirus tests.) They’re dressed in drag — even mustaches — caricaturing their male detractors. We’re in for a tedious history lesson, these hypothetical skeptics predict in song; a dreaded feminist is “planning to scold you for three hours straight.”My first thought: Dear God, I hope not.“Suffs” has a hefty two-hour-and-45-minute running time, after all, and though the musical isn’t guilty of scolding, it is guilty of stifling an impressive — though exhausting — breadth of U.S. history through its contemporary lens.Shaina Taub, the Public Theater’s playwright in residence and creator of the musical, stars as Alice Paul, the headstrong young suffragist who assembles a group of women who lead protests, suffer abuse and incarceration, and march on Washington for their right to access the ballot box.Taub gives a steely performance as Paul, though her standby (Holly Gould) has stepped into the role, as Taub tested positive for the coronavirus just before the production’s scheduled opening.Hannah Cruz, center, in the satirical vaudeville-inspired number “Watch Out for the Suffragette!” in the show.Sara Krulwich/The New York TimesPaul is joined in the metaphorical barracks by Lucy Burns (played by an understated Ally Bonino), her friend and fellow suffragist who helped Paul form the National Woman’s Party. There’s also Doris Stevens (Nadia Dandashi, teeming with earnestness), an eager young student and writer from Ohio, and Ruza Wenclawska (a droll Hannah Cruz), the tough-as-nails Polish American factory worker and union organizer. Inez Milholland (Phillipa Soo), a labor lawyer and chic socialite, is their public face; as Inez, Soo, the beloved “Hamilton” alum, brings sugar, sass and style to the group, marching with a cocktail in one hand and a cigarette in the other.In the seven years that are covered in the musical — 1913 to 1920, when the 19th Amendment was finally ratified — Paul butts heads with her sisters in the fight. She has a yearslong dispute with Carrie Chapman Catt (Jenn Colella), who, as the head of the National American Woman Suffrage Association, thinks Paul’s moves are too radical. And there’s the journalist and suffragist Ida B. Wells (Nikki M. James), who unsuccessfully tries to bring race into the movement, challenging Paul’s myopic vision for change.But her actual opponent is the president, Woodrow Wilson (Grace McLean), who noodles around the stage, step-kicking down stairs with a top hat and a cane while gaily singing misogynistic lyrics like “Men make the money/Ladies make the bread/Men make the rules/Ladies make the bed.” McLean’s jaunty performance introduces some of the few moments of levity in the musical; otherwise a general stiffness pervades the production.Nikki M. James, center, as Ida B. Wells and Cassondra James, right, as Mary Church Terrell in a subplot highlighting the tensions between two suffragists with differing ideas about how to elevate race in the movement.Sara Krulwich/The New York TimesMaybe that’s because the whole production feels so attuned to the gender politics and protests of today, so aware of possible critiques that it takes on its subject with an overabundance of caution. So a mere 20 minutes into the show, “Suffs” makes it clear it’s not framing Paul as the perfect warrior-saint of the movement. When Paul is dismissive of Wells she responds with the song “Wait My Turn” (“Do you not realize you’re not free until I’m free./Or do you refuse to see?”), establishing her role as the racial conscience of the musical, popping up every once in a while as a reminder of the pitfalls of white feminism. And all these women and stories of their activism are uncomfortably stuffed into a show too scared to miss anything that it becomes bloated with information.In many ways “Suffs” lands like a clunky heir of the Public’s other big historical musical, “Hamilton,” borrowing some of its approaches to structure while trying to avoid the criticisms about its politics around women and slavery. But that’s the risk that comes with recasting history with today’s sensibilities in mind. Even this feminist tale occasionally serves retorts to those funky founding fathers who met in “the room where it happens”; our suffragists sing about how no women got to witness the signing of the 19th Amendment themselves because “a man signed the paper behind a closed door in a room somewhere.”But the musical doesn’t need to try so hard to defend itself or prove its relevance, say, by showing the threats and taunts of men interjected into songs like “The March.” Neither does it need to fall back on preciousness, like when a Tennessee state senator’s mother, an “old farmer’s widow,” sings a banjo-heavy song pleading with her son to vote for suffrage with a promise of his favorite meatloaf in return. Or the pat pairing of some couples in the end, and the heavy-handed finale, “Never Over,” about the continuous march toward progress.The direction, by Leigh Silverman, feels as methodical as the text; the pacing is speedy, and the songs are dense with exposition like those of “Hamilton.” But “Suffs” turns out to be all work and mostly no play, and when it comes to the music itself nothing really pops. There are a few dry touches of vaudeville, and pop and some sugary songs like “If We Were Married,” a number that feels like a contemporary stab at Fred Astaire and Ginger Rogers’s 1937 rendition of “Let’s Call the Whole Thing Off.” It’s a parody of such cutesy courtship numbers yet it delivers just that.Taub, left, as Alice Paul and Jenn Colella as Carrie Chapman Catt, who thinks Paul’s moves are too radical.Sara Krulwich/The New York TimesThe music is most interesting when it sheds the exposition and allows the characters space to express their hopes, frustrations and desires. Colella slays her performance in one such song, the prickly “This Girl.” Colella clips her words and sharpens her gestures, hitting her notes with the punch of a boxer in the ring. The harmonies, too, like those in the ensemble number “How Long,” which shifts from a tone of despair to one of resilience, also provide the music with much-needed dimension.The choreographer Raja Feather Kelly’s typically transgressive style (exhibited in shows like “A Strange Loop” and “Fairview”) feels defanged, ball-and-chained to its very literal interpretation of the material; there’s much marching and posing, syncopated stepping. Mimi Lien brings a similar austerity to her set design — the stately steps and columns of Congress, perhaps, or some institutional building — but the simplicity here works, allowing “Suffs” to focus on its diverse cast of history-makers. In the costume design, Toni-Leslie James strikes a satisfying balance between formal high-waisted skirts and black lace-up boots, and the splashy wide-brimmed hats have enough ribbons and feathers to make a Southern churchgoer swoon.“Suffs” ends with a passing of the torch from one generation of change-makers to the next, revisiting the latest clash of new politics versus old politics: What was once revolutionary becomes out of date. For all the work this show does to illuminate the successes — and failures — of the women’s rights movement, and the constantly evolving nature of our politics, it focuses so much energy on seeming as timely as possible. But, as the suffs learn, movements transform; our government leaders change, as do the demands of the people on the picket line. It’s a lesson the musical should take to heart: You can’t live in the past, present and future of our nation’s politics all at once — at least not without losing your way.SuffsThrough May 15 at the Public Theater, Manhattan; publictheater.org.
