If you’ve ever wondered, wonder no more. I found a video explaining it all to us. If you dont know what Room 237 is let me quote wikipedia.
Room 237 is a 2012 American documentary film directed by Rodney Ascher about interpretations and perceived meanings of Stanley Kubrick’s film The Shining (1980). The film has nine segments, each segment focusing on different elements within the film which “may reveal hidden clues and hint at a bigger thematic oeuvre.”
If you don’t know what Pitch Perfect is then this will probably make you want to see it. The depth of this movie is so big that it’s insane.
