The surface story of The Shining is well known: Jack Torrance, a writer with a drinking problem, takes a job as winter caretaker of the Overlook Hotel in the Colorado Rockies, bringing his wife Wendy and telepathic son Danny. The hotel is built on an Indian burial ground. As the winter isolation deepens, Jack descends into madness — or is possessed by the hotel's malevolent spirit — and attempts to murder his family. Wendy and Danny escape. Jack freezes to death in the hotel's hedge maze.
Stephen King, whose 1977 novel provided the source material, publicly and consistently expressed his dislike of Kubrick's adaptation — arguing that Kubrick had hollowed out the novel's emotional core, made Wendy into a passive victim, and replaced genuine supernatural horror with cold psychological ambiguity. King's criticism is accurate as a description of what Kubrick did. It misses why Kubrick did it. Kubrick was not adapting King's novel. He was using King's novel as raw material for an entirely different project.
The question that organises everything that follows: if Kubrick stripped out everything that makes King's novel emotionally resonant and replaced it with geometric impossibilities, subliminal imagery, infrasound, and a dense network of symbolic references — what was he building instead?
