Sometimes advertising and packaging can make you ill-prepared for a movie.  I know that M. Night Shyamalan’s Unbreakable, Split, and Glass are considered a trilogy.  Without knowing the story, I saw the first film and discovered it was a superhero movie.  That’s fine, of course.  It’s not really horror much at all.  That’s maybe the reason Split caught me off guard.  It is brought into sequel territory right at the very end, but the story is tense and scary.  Kevin Crumb is a man with DID, dissociative identity disorder—what used to be called a split personality.  Quite apart from the inherently fascinating phenomenon (and the criticism the movie received for misrepresenting it), the idea that a person shifts and you don’t know who s/he is, is frightening.  A couple of those personalities have teamed up and become criminal.  Kevin abducts three teenage girls for a purpose that only becomes clear later.  Their efforts to escape create a great deal of the tension, and the quick shifting of identities that Kevin displays makes any kind of reasoning with him impossible.  

There are any number of avenues to discuss here.  One is that Kevin’s disorder stems from how his mother treated him as a child.  (Unintentionally I’ve been watching movies that trigger me that way lately.)  He developed personalities to protect himself from the pain and they continue to multiply.  Meanwhile, the kidnapped girls can’t figure out what’s going on but Casey (Anya Taylor-Joy—my first clue that this was horror instead of a superhero movie—)realizes that she has to treat the different identities in different ways.  Another avenue is to consider what “the beast” (one of the personalities) asserts: only those who’ve been broken are truly evolved.  Some children make it through difficult childhoods by becoming resilient while others don’t.  Casey, it turns out, also had an abusive relationship in her childhood.  Movies like this always make me reflect on how difficult being a good parent can be.

The person not in control of their own actions (ahem) is among the most frightening of human monsters.  Those with mental illness, however, seldom fall into this category.  I understand why mental health providers found this film problematic, but it showcases Shyamalan’s horror chops.  It was the scariest movie that I’ve seen in quite some time.  After I ejected the disc I felt bothered (and trapped) for quite a few minutes.  And I realized that if this is a trilogy then superhero and horror combined await in the third part.  We shall see.
