I love all the books you listed, but I agree about Joyland being overlooked. Seemed like everyone kind of ignored Joyland because they were excited for Doctor Sleep (not the people on the boards, I mean the reading public in general).
I also think part of the reason Joyland is also overlooked is that it was issued as a trade paperback, not a hardcover, for the general public. It didn't seem to get the hype it would have gotten had it been a hardcover.
