Kevin, who has a split personality (there are 24 different personalities in his head), kidnaps several girls. With Split, the director of The Sixth Sense and The Village, M. Night Shyamalan, rehabilitates himself after several big-budget flops — and as various movie critics have pointed out, he does it in style. Here, Shyamalan ratchets up the gloom and mystery to the point where you simply have to see this movie in a theater.
