I seem to remember that Stephen King was never a big fan of Stanley Kubrick's adaptation of The Shining, stating that Kubrick missed the point of the story and shifted its emphasis from the inherent evil of the hotel to a mere human drama (he even went as far as supervising a supposedly more accurate TV-adaptation in the 90s).
He was staring into the doorway, hypnotized, as an aisle of Macy’s rushed forward—he was reminded again of The Shining, where you saw what the little boy was seeing as he rode his trike through the hallways of that haunted hotel. He remembered the little boy had seen this creepy pair of dead twins in one of those hallways. The end of this aisle was much more mundane: a white door.
Now this is surely just a short throwaway reference. But not only is he referencing a film adaptation of one of his very own works (which, given the broader work-spanning universe supposedly established in the Dark Tower series, might lead to interesting continuity problems if concepts from The Shining would ever find their way into that shared universe). He references one he is known for not holding in a particularly high regard.
So is there anything known about the nature of this reference and how it came about or what its wider implications about The Shining's place in the Dark Tower series and especially King's opinion about Kubrick's film are, if any? Can we draw more conclusions from the text (or any future books in the series) or any other of King's statements about the Kubrick film that make more of this very odd choice of reference, or is it supposed to be just that and nothing more?
