There are two things that you expect from any M. Night Shyamalan (The Visit) film. The first is tight construction that leaves virtually no thread loose by the end of the film. Split certainly delivers on its tight plotting. Shyamalan is also known for his twist endings. And, for a change, this movie doesn’t rely on that. There are gifts and surprises in the film, but no real twist. Instead we get a well executed suspense/thriller that is riffing on some very real movements in the Dissociative Identity Disorder (DID) community.
This film also continues Night’s push into small, intense stories with few characters. In this case, it is really driven by three actors. First and foremost is James McAvoy (Victor Frankenstein), who does a great job of flipping between identities. Anya Taylor-Joy (Morgan) holds her own against him, both directly and in her own scenes, as she attempts to survive while revealing her past to us. Finally, there is the great Betty Buckley who strikes the perfect tone of a caring but driven psychiatrist. The dance of these three characters is tense and, ultimately, explosive.
It is almost impossible to say more without slipping and giving away information, so I’ll wrap here. I had several points spoiled for me by ads and internet babble. Frustrating. Avoid all info if you can before watching it. If you like Shyamalan’s films or just good, tense thrillers, throw it in the hopper or turn on the stream. You won’t be disappointed.
