Fans of Chainani’s books may relish seeing his inventiveness and heartfelt storytelling on a (green) screen. If only Feig had the latitude to prioritize his actors, rather than his VFX team, as those storytellers.

While the talented and versatile director Paul Feig (“Freaks and Geeks,” “Bridesmaids,” “A Simple Favor”) displays an admirably ambitious reach, and there are some impressive visuals, The School for Good and Evil never quite finds its footing.

The real magic of “School” resides in its stars. Caruso loses Sophie’s moral direction in deliciously fun yet behaviorally alarming ways. Wylie finds Aggie’s righteousness without damaging the character’s cunning intellect; a scene involving “wish fish” has no business being as moving as Wylie makes it. Together, the young actors take this project beyond good and evil, into the realm of something real.

Mildly diverting from time to time due to its beautiful production design, The School for Good and Evil is mostly an unmitigated slog, filled with underdeveloped characters, absolutely terrible dialogue, and a world that feels both completely ripped off from better things and unnecessarily complex.

The film doesn’t have the space to expand all of its ideas and gracefully unfold its plot, which is full of so many narrative twists and reversals that The School for Good and Evil equates to a whole TV season untidily packed into a feature film.
