The site offers this simple written explanation, If Stephen King haunts the Stanley Hotel, who haunts Stephen King? The answer is: Stanley Kubrick. King didn't like Kubrick's movie ("a Cadillac with no engine in it"); he didn't like Jack Nicholson in the main role; years later, he readapted The Shining as an ABC miniseries; but nobody cares about that. The movie scared people silly, once and forever.
