Stanley Kubrick’s The Shining has made way for a number of theories trying to explain what happens at the Overlook Hotel and what the story really means, and among them is a theory that explains the real reason why the Grady twins were killed. Many of Stephen King’s works have been adapted to other media, sometimes more than once, as is the case of The Shining. Directed by Stanley Kubrick, The Shining was released in 1980, and while it’s now regarded as one of the best horror movies ever made, it was initially received with mixed reactions due to its tone, the changes it made to King’s story, and its symbolism, ambiguities, “mistakes”, and the unanswered questions it left.
