I'm curious if you've read the book, because I read it before seeing the movie (Compared to 2001 where I saw the movie first) and the movie just isn't even close to being as good as the book. I've always wanted to go back and give the movie another shot but I honestly don't think my opinion would change much.
The quote from Stephen King says it all:
"Parts of the film are chilling, charged with a relentlessly claustrophobic terror, but others fall flat. Not that religion has to be involved in horror, but a visceral skeptic such as Kubrick just couldn't grasp the sheer inhuman evil of The Overlook Hotel. So he looked, instead, for evil in the characters and made the film into a domestic tragedy with only vaguely supernatural overtones. That was the basic flaw: because he couldn't believe, he couldn't make the film believable to others. What's basically wrong with Kubrick's version of The Shining is that it's a film by a man who thinks too much and feels too little; and that's why, for all its virtuoso effects, it never gets you by the throat and hangs on the way real horror should."
Maybe he goes a little hard on Kubrick there, but ultimately I think he's right. He made the movie too much about Jack Nicholson's character instead of the, uh.. forces of the hotel. Also he basically rewrote the ending and it's not nearly as good as what transpired in the book.
