TL;DR: Split is a high-intensity psychological thriller that’s technically a superhero origin story in disguise. While it’s rated PG-13, it deals with heavy themes of childhood sexual abuse, kidnapping, and a very controversial portrayal of Dissociative Identity Disorder (DID). It’s not "brain rot," but it is "brain-heavy." If your teen is into Stranger Things or psychological puzzles, they’ve likely already seen clips of James McAvoy’s performance on TikTok.

Released in 2016, Split is the second installment in M. Night Shyamalan’s "Eastrail 177" Trilogy, sandwiched between Unbreakable and Glass.
The story follows three teenage girls who are kidnapped by Kevin Wendell Crumb, a man diagnosed with Dissociative Identity Disorder (DID) who has 23 distinct personalities living inside him. The tension comes from the girls trying to manipulate these different "people" (ranging from a nine-year-old boy named Hedwig to a stern woman named Patricia) to find a way out before the arrival of a rumored 24th personality: "The Beast."
While the movie was a massive commercial success, it’s basically the "Ohio" of mental health representation—weird, slightly nonsensical, and definitely not grounded in reality. It treats a real-world disorder as a supernatural superpower, which is where most of the parent-level "yikes" comes from.
If your teen is asking to watch Split, it’s probably for one of three reasons:
- The McAvoy Factor: James McAvoy’s performance is objectively incredible. He switches between personalities with just a facial twitch, and clips of these transitions are constantly circulating in "acting challenge" videos on social media.
- The "Twist" Culture: Shyamalan is the king of the twist ending. Teens who grew up on YouTube theory channels love movies that feel like a puzzle to be solved.
- The Connection to Glass: Since Glass brought together the worlds of Unbreakable and Split, there’s a "completionist" urge to see the whole story, much like the MCU.
Let’s be real: Split is not a documentary. It’s not even a particularly sensitive drama. It’s a comic book movie masquerading as a thriller.
The film’s central thesis is that people who have suffered immense trauma are "evolved" or "more" than those who haven't. While that sounds poetic, the mental health community was—rightfully—pretty annoyed. By portraying someone with DID as a literal flesh-eating monster, the movie leans into the tired "mentally ill person as a violent villain" trope.
If your teen watches this, they need to know that DID is a real, often debilitating condition that usually results from severe trauma, and it almost never involves people turning into wall-crawling beasts. It’s a good moment to check in on their media literacy.
The PG-13 rating is what we call a "hard" PG-13. It’s not about the gore—though there is some—it’s about the psychological weight.
Ages 12 and Under
Hard No. The themes of kidnapping, forced undressing (the girls are told to take off their shirts, though nothing sexual is shown), and the sheer terror of the "Beast" are too much. It’s the kind of movie that creates a "new fear unlocked" moment for younger kids.
Ages 13-15
Proceed with Caution. This is the target demographic, but it depends on your kid's "spook factor" tolerance. If they handled Stranger Things or A Quiet Place fine, they can likely handle the tension here. However, be prepared to talk about the trauma themes. The protagonist, Casey, has a backstory involving childhood sexual abuse (shown in flashbacks), which is the real emotional core of the movie.
Ages 16+
Green Light (with a chat). At this age, they can appreciate the filmmaking and the acting while critiquing the problematic portrayal of mental health. It’s a great "film school" movie to watch together.

Violence and Gore
It’s mostly psychological, but the final 20 minutes go full horror. There is a scene where a character is crushed, and another where "The Beast" eats someone (off-screen, but the sound effects and blood are plenty). It’s visceral.
Sexual Content
There is no nudity. However, there is a pervasive threat of sexual violence that hangs over the first half of the movie. The girls are kept in a basement and told to undress. While the movie subverts this (the villain has no sexual interest in them; he’s "cleansing" them), the implication is terrifying for a young viewer.
Language
Standard PG-13 fare. A few choice words, but nothing that’s going to shock a kid who has spent five minutes in a Roblox voice chat.
If you decide to let them watch it, or if they’ve already seen it at a friend’s house, here are a few ways to open the conversation without being the "lecture parent":
- On Mental Health: "So, Kevin’s 'Beast' personality gave him super strength. Obviously, that’s not how DID works in real life. Why do you think the director chose to make a mental illness look like a superpower?"
- On Trauma: "The movie says that 'the broken are the more evolved.' What do you think about that? Does suffering actually make someone 'better' or just different?"
- On the Twist: "Did you see the Bruce Willis cameo at the end coming? Do you want to see Unbreakable to see where it started?"
If the kidnapping and "Beast" stuff feels like a bit much, but your teen loves a good mystery or psychological thriller, try these:
- Inside Out 2: Stay with me here. If you want to talk about "different personalities" or "emotions" running the show in a way that is actually psychologically sound and not terrifying, this is the gold standard.
- Knives Out: For the teen who loves a "puzzle" movie with a great ensemble cast and a twist you don't see coming, without the trauma.
- The Truman Show: A classic psychological thriller that deals with reality and perception without being a horror movie.
- Everything Everywhere All At Once: If they want that "superpower/trauma" connection but with a much more inclusive and beautiful message.
Split is a well-made, gripping movie that is unfortunately built on some pretty shaky (and stigmatizing) ground regarding mental health. It’s a "Hard PG-13" because of the psychological intensity and the backstory of abuse, not because of "F-bombs" or gore.
If your teen is mature enough to separate movie-monster-logic from real-world-people-logic, it’s a fascinating watch. If they’re still prone to nightmares about people under the bed, maybe stick to Coolmath Games for the night.
