Holy cow. My mind is blown. Everything from the title, to the director dying 5 days after submitting the final cut, to the location chosen to film the cult party. These links are a long read but a great explanation of the movie.
So many unbelievable things that I've come across in this group are confirmed by this movie. I saw someone mention it in a comment months ago and glad I finally came around to watching it. It was very strange in the beginning, but you have to remember you're not watching a regular movie, you're watching someone trying to show you what's going on without explicitly saying it. After reading the above articles I am just blown away.
Fun fact: Kubrick had a 4 hour+ work print of EWS.
After Kubrick's death Steven Spielberg was brought in by Warners to "trim up" the film to be presentable to an audience.
There is no doubt Kubrick's true vision of the movie is not the one we are being shown.
