Room 237 is a documentary about interpretations of Stanley Kubricks The Shining. I heard it was well received at some film festival and I was looking forward to catching up with it as I'm familiar with the film, Kubrick's style of leaving messages and coded thoughts/secrets and most of all I've been following Jay Weidner's analysis on this subject for a year or so.
Sadly I've overdone it and this documentary was badly made, boring and prone to waffle and pseudo interpretations that at times trailed off with children in the background of phone interviews.
I've written a review of The Shining here if you want to get into earlier thoughts on the subject. There's also a recent interview with Jay that takes his thinking even further and is a must listen on the topic.
