The scary kind of “postmodern”
Yes, The Shining is a Great Movie. Even Roger Ebert says so.
There is a phenomenon in religious studies called the Antiquity Effect—the older a text is, the more profound it is. (There is also a Vagueness Effect—the more uncertain the meaning of a text, the more profound it must be because our efforts at penetrating it keep failing.)
The Shining is now 38 years old, Kubrick is dead, and both seem to have passed over into Antiquity and have gained præternatural status. Put a præternatural natural object into the hands of an imaginative redneck, and all sorts of interesting discoveries are bound to arise. The Bible is a good example. Rednecks really believe that things used to be very different. People lived for hundreds of years. Yahveh frequently spoke to people and performed miracles. Humanoids with six wings and four faces flew in the sky, as did “wheels,” which of course were UFOs.
The Shining has become a redneck bible, admitting of various insane interpretations, most declaring it to be a secret message. (Why secret? Poor Kubrick had to speak symbolically, otherwise They would kill him or his family.) In fact there is a new documentary, Room 237 (2012) that collects nine such interpretations. One of them is very popular with rednecks. According to Jay Weidner, the film is an expression of guilt. We never landed on the Moon. Kubrick faked the whole thing, and The Shining is his confession.
The Moon landing was a simulacrum manufactured by a cabal of deceivers. For what end? In part, to keep people enthralled by the lie that the Earth is not flat.
