I couldn't even finish Fairy Tale. King's kids have gotten to be pure tropes these days. I think King tries to give characters and especially kids, some very specific tics and slang to make them "unique" in a place and time. And then he just over-does it to the point of caricature. Almost like he's making them "overly unique."

His "good" kids are so overly earnest and respectful that they just become very phony.

I'v had this problem with King since the 1980s. I vastly prefer his short stories versus his novels since the mid '80s. There's less of this caricature building.
