Ethan Herisse and Brandon Wilson star in RaMell Ross's film, adapted from Colson Whitehead's Pulitzer-winning novel.

It's harder to adapt a great book than an average one. Literary greatness often inhibits directors, who end up paying prudent homage to the source rather than engaging in the bold revisions that successful adaptations require. And even uninhibited directors may lack the stylistic originality of their literary heroes. It's all the more remarkable, then, that the director RaMell Ross, in his first dramatic feature, "Nickel Boys"-adapted from Colson Whitehead's Pulitzer-winning 2019 novel, "The Nickel Boys" avoids both obstacles with a rare blend of daring and ingenuity. Few films have ever rendered a major work of fiction so innovatively yet so faithfully. In a year of audaciously accomplished movies, "Nickel Boys" stands out as different in kind. Ross, who co-wrote the script with Joslyn Barnes, achieves an advance in narrative form, one that singularly befits the movie's subject-not just dramatically but historically and morally, too.
