Split is M. Night Shyamalan’s psychological thriller that marked a true return to form.

The film centers on Kevin, a man with 23 distinct personalities—and a 24th, known only as “The Beast,” waiting to emerge. James McAvoy delivers a tour-de-force performance, effortlessly switching between identities ranging from a prim woman to a 9-year-old boy to a cold-blooded predator. It’s unnerving, mesmerizing, and at times even darkly funny.

Anya Taylor-Joy adds emotional weight as Casey, a kidnapped girl with a haunting past of her own. The tension builds steadily, and while some scenes border on absurd, Shyamalan keeps you hooked with tight pacing and eerie atmosphere.

The film’s biggest moment comes in the final minutes, with a twist that links it to Unbreakable, blowing the minds of longtime fans.

Final score: 8 out of 10. A gripping thriller elevated by McAvoy’s insane range and a perfectly placed twist.
