One thing people seem to be good at is arguing over texts. We can argue different points about the same information. How many interpretations are there for the constitution? And that’s just one language. Hit up the Torah, Bible, or Koran that’s been translated into different languages a few times and it’s absolute chaos. People seem to focus on minutiae instead of the big picture.
I can easily imagine a post-apocalyptic dystopian future where the Star Wars films have become the basis for religion. People will subscribe to their own versions of the Jedi and Sith philosophies and have an overall high regard for the force. Some people will say it’s all fiction. Magicians will use levitation and spoon-bending illusions to “prove” that the force is real.
I can imagine sects breaking out of each group of trilogies, finding their own interpretations of the overall themes to be the only correct way to see things.
Some will say Anakin/Vader brought balance to the force. Some will say it was Luke. Some may focus on the new characters to come. Some cults will say you have to go to the dark side before you can be redeemed by the light and that is the only true path to Jedi salvation.
Some will argue that the original films unedited are the only true word. Some will argue that the standalone films and animated series are like the apocrypha, and can’t be true canon.
Monasteries will open and instead of vows of silence, they will talk like Yoda.
Books will be written trying to prove that the holiday special did in fact exist.
People will kill each other arguing over who shot first.
I think you now have a script for Idiocracy 2: Idiocracier.
