The cast couldn’t be better. Making her Broadway debut, Maleah Joi Moon is a find, with stunning vocals and just the right mixture of irritability and vulnerability. Without affect, she effortlessly lives the part up on that stage. Shoshana Bean (Mr. Saturday Night) is a marvel as her overprotective mother, rooting the show’s dramatic conflict and singing so amazingly, she turns Jersey’s pain into showstopping moments. As her seemingly good for nothing musician ex (and Ali’s dad), Brandon Victor Dixon is perfection, always trying to be less absent, including on an impressionistic version of Fallin’ that he deliciously sings to Jersey in a last-ditch effort to win her back. And Kecia Lewis is terrific as Miss Liza Jane, though she has to emit some dialogue people would normally never say. (“Your rage is real. Your rage is earned. But I will not let it defeat you.”)
