ANY other director but Kubrick, and I would agree with you.
But Kubrick was fully aware of making puzzle films for the masses, and knew how people were trying to read into "2001." So maybe he just decided to add some confusing elements to THE SHINING because he absolutely detoured from King's book, and even the actual physical hotel that he could have used, as King's miniseries did. I can believe he made a film that on one level is just a surreal horror film. But on another, hidden level, was much more. We are talking about someone who was supposedly more intelligent, than most of us are. Kubrick played chess to make money. Could you do that?
So you may think that these people are crazy with their theories. And I'm not convinced about all of them - but I think the truth is somewhere in the middle. The Native American motifs/package labels/decorations/prints/rugs were all chosen by Kubrick. So either he was really into Native American imagery (not as prevalent in any of his other films, so I would say "no") or, he was using them for a reason.
The Kubrick film IS far superior, in every way.
