Loved the Kubrick version since forever, my spouse needled me into finally reading the novel. Very well executed, very Stephen King-y horror.

One thing I found interesting is how the movie and book treat differently the moral agency of Jack Torrance as he descends into murder and mayhem. The Kubrick film, to me, commits to an ambiguity of whether we are seeing the actions of "Jack Torrance", perhaps amplified by the evil spirits in the Overlook. It feels like the horror we are seeing is part of Jack, that he is at least somewhat responsible for what he does.

Whereas the novel tells us very explicitly that Wendy and Danny believe they are no longer seeing Jack, but "The Hotel" in Jack's body is menacing them. I have a longer harebrained theory about what this means for Jack's character, but it's an interesting difference either way
