Insomnia is a 1994 horror/fantasy novel by American writer Stephen King. It follows retired widower Ralph Roberts whose increasing insomnia allows him to perceive auras and other hidden things, leading him to join a conflict between the forces of the Purpose and the Random. Like It and Dreamcatcher, the story is set in the fictional town of Derry, Maine. It includes connections to other Stephen King stories, particularly his novel series The Dark Tower.
I've never read the book, but perhaps this criticism applies to the book as well. King certainly has a tendency to push fetishized characteristics that take the place of earnest characterization. This is certainly true of the Stand, the Dark Tower series, the Shining, Insomnia, Green Mile, and probably many others of his works. This is not an original take.

It's so weird.
