This may not be M. Night Shyamalan’s worst movie, though it’s surely his most disappointing. The writer-director brings together the principal characters of his Unbreakable (2000) and Split (2016), two entertaining films that presented comic book-style fantasies in a subdued manner and in believably grim urban settings. Unfortunately he doesn’t have anything new to say about the characters; he just surrounds them with other people who discuss what their stories might mean in long stretches of ponderous, flat-footed dialogue. These conversations basically spell out the subtext of Shyamalan’s earlier films, as though the filmmaker thought his viewers were too dumb to figure it out for themselves; even worse, they treat the mythology of those films with such un-self-conscious reverence that they suggest the filmmaker is terminally infatuated with his own work. The saving grace is Shyamalan’s camerawork and visual compositions, which are as striking and expressive as ever; for all his faults, he remains one of the only contemporary Hollywood directors who genuinely believes in mise-en-scene. With James McAvoy, Bruce Willis, Samuel L. Jackson, and Sarah Paulson.
