Ironic I just saw the Simpsons parody of it on tv two night ago. I LOVE the Shining, it's one of my favourite horror movies. I read the book too. Here's something to look out for: notice how when Jack talks to a butler or any other character in the hotel besides his family and the caretaker, that there is always some sort of a reflective surface (ie a mirror) behind the 'person' he is talking too. Like with the butler when he's talking to him in the washroom, there's a mirror behind him. Meaning that Jack is hallucinating and is actually only talking to himself although he may appear to be talking to someone else...it's not really much to look out for but it helps explain the plot more, and I just noticed that the last time I watched it.
Yeah watch out for the lady when she comes out of the bath, that part mortified the socks off me. For me, the worst part is whenever those girls appeared...
