• It’s because they’re not horror, and SK is known best for his horror. I do think he’d said, at one point, that TDT was the most meaningful series to him, and the fact that it forms an umbrella reality encompassing all of his other stories - sometimes featuring characters from his other novels, is significant.

    That said, I’m not a King fan; I don’t much care for horror, so his money making genre isn’t very compelling for me. But I did get super-into The Dark Tower. It’s up there among my favorite works, despite the ending.
