Man, I'm watching this again right now and the thing that strikes me is how seriously screwed up this family is! Even the beginning of the movie, before all the crazy stuff starts happening. Clearly "Tony", the kid's imaginary friend is his subconcious. The idea of spending a winter in the overlook with his dad is traumatic to him. So much so, that he goes into a fit at the thought of it. And no wonder - Wendy (his mom) tells the pediatrician that comes that his dad dislocated the kids shoulder in a drunken rage a few months before.
Christ, what the hell is wrong with this pediatrician? Wendy is clearly an apologist for an abusive husband and the kid is already traumatized. And she just sits there saying these "episodes" in kids are very common, and "Kids can scare you to death".
IMO, the whole ghost story aspect is a smoke screen, and it's really about a physically abusive alcoholic destroying his family.
"THIS is where we keep all of our MEAT."
