Split: The Thriller That Was Secretly Something Else
★ 8.5major
M. Night Shyamalan's 2016 thriller follows a man with 23 distinct personalities and the three teenagers he's abducted, building toward a 24th persona his therapist fears more than any of the others. What the film is quietly doing with that fear -- and what it reveals about its own genre in its final scene -- is not what the marketing prepared audiences for.
