It also seems to help that Split is not a puzzle movie, that nebulous subgenre inspired by The Sixth Sense and Christopher Nolan's Memento, which rewards the viewer for piecing together the plot from a slow dribble of ambiguous information.
Ever since he made “The Sixth Sense,” his one good movie and far and away his biggest hit, writer-director M. Night Shyamalan has been attempting to rekindle the fire.
Stark and soaked in dead-silent tension, the short recurring sequences build a sense of dread that’s woefully absent from the rest of the movie, an eerie reminder of Shyamalan’s no-kid-gloves approach to childhood trauma in The Sixth Sense and other films.
Nevertheless, the more significant and spoiler-proof astonishment here is that Shyamalan — after nearly a decade-long creative (and sometimes commercial) drought — has reclaimed much of the formal precision and conceptual daring that made his earlier pictures, “The Sixth Sense” and “Unbreakable” chief among them, so memorably creepy.
But Split does unify Shyamalan’s films in other ways, specifically through its three biggest themes, which thread throughout most of the other movies he’s written and directed, from The Sixth Sense and Unbreakable to The Village and The Visit .
It's the sort of outlandish setup one might expect from The Sixth Sense mastermind M. Night Shyamalan, and thanks to inspired turns from Taylor-Joy and Scottish actor James McAvoy, Split is often as engrossing as it is implausible.
