Hero
I've read very little "modern" King, but I know the pagecount on the later books of the Dark Tower series ballooned tremendously, and not (IMO) for the better. At the time I felt it was probably a reaction to his accident - he was more indolent of his writing, and his editor was more lenient. I don't have any proof of that (except that once he started writing again, the first stuff out the gate were those books, and the accident was pretty transformative for him). The market has changed, though - mega-novels are the norm; Murderbot novellas the exception.Interestingly I see a lot of similarities to Brandon Sanderson: Incredible high output and writing discipline, close contact to their fandom, always open for new marketing techniques (King was one of the first ebook pioneers), very popular and bestselling - but not that great with the critics (although that changed for King in his later career and the same is true for Sanderson), huge pagecount per book, slow pacing etc.
If you like horror, dive into the short stories. He can and did write shorter stuff.
