Derry in the book is a diseased place representing everything wrong with a small to mid sized American town. People participating in and enabling racism, homophobia, child abuse, and everything else you can think of. IT feeds off of this like a parasite, and the adults (plus kids like Henry) are complicit in its periodical reigns of terror. The film has some of this stuff, but never goes far enough for it to come to the forefront in order to drive the point home and make the viewer genuinely uncomfortable. There's only one scene of adults ignoring Henry's bullying. The farthest we get into racism is one scene where Henry calls Mike an "outsider". No one says the N-word, we don't delve into the racial motivations behind the Black Spot, we don't see Henry kill Mike's dog then get a pat on the back from his racist dad about it. Bev's dad is creepy, but he never escalates into full blown child abuse until near the end of the film. The end result is that Derry lacks any sort of character as being this awful pit of evil that IT would gleefully nest in, instead it's just a town with some creepy buildings where stuff happens. It feels like a lot of this was excised because the producers were scared at the idea of making any viewers genuinely uncomfortable with anything outside of IT's multiple scary and gross forms. I watched the RedLetterMedia review of the film after getting home, and their half-criticism of calling this a "marketable film" is very on point in that regard.
