Stephen King is kind of a funny author. Some of the stuff he writes is pretty good and some of it really flops around with story elements that are far too long and story elements that don't really get resolved, and story elements that take away from the overall quality of the story.

His underlying story ideas tend to be pretty good but his writing is all over the place. He can write one story that's decent while the next story is a hot turd he just squeezed out. And yet somehow he's still managed to become very successful.
