They way I see it, the jump scares and Pennywise are there for the kids and teens; they are fun for adults, too. The real horror for adults, though, is the peripheral and more insidious evils: racism, toxic masculinity, bullying, child sexual abuse, Munchausen by proxy, and the kind of apathetic indifference that leads adults to turn a blind eye to those forms of evil and suffering. If you weren't horrified by the leper, for example, you were sickened by Eddie's mother making her son believe he was ill. If a headless victim of the Ironworks tragedy wasn't scary, the blurry grinning woman in the background did the trick. Blood in the sink? No match for Beverly's perverted father. Burned hands in a doorway and zombie children not scary enough? The lady talking to the kids on television is acting weird and isn't that pharmacist a bit too friendly with little girls? Henry's dad, the cop, is scary. Adults bully kids who become bullies themselves. That's the fertilizer It needs to grow children with fears It can eat with relish. That's the stuff of nightmares.
