Just watched Room 237 on netflix. It's a documentary about The Shining and people who have some pretty elaborate theories about the hidden messages that Stanley Kubrick embedded into the film. Some of the stuff makes sense and seems somewhat obvious, but some of it is far reaching. But I've always loved The Shining, so I thought this was really interesting. If you aren't really familiar with it this doc would be filled with spoilers and probably be hard to follow.
