I went into Room 237, a documentary about The Shining, with the same hopes with which I'd enrolled as an English major. I wanted to learn some of the tricks of Kubrick's trade, discover how he created such a timelessly unsettling and horrifying motion picture. Instead, I got a bunch of people BS-ing about Kubrick's hidden conspiracy theorizing, his hidden messages about the Holocaust and the Indian Wars, and God knows what else.
I learned nothing. I learned nothing about why Kubrick chose to change key elements of Stephen King's novel in its transition to the screen. I learned nothing about why he plotted The Overlook's interior spaces as he did, or whether various impossibilities were oversights or techniques to disorient the viewer. I learned nothing about his choices in lighting, or framing, or music.
I just got a bunch of obsessives blathering about their pet interpretations for an hour and a half. I could have gotten that in any junior-level literature class in any state university in America.
