This is a very interesting concept. I see in your replies to other comments that you are looking at movies from different cultures, which would be a great test of your idea. Once you have sufficiently advanced, it would be great to look at theatre too. I have a hypothesis that movie-writing began to diverge from theatre-writing in the very late 20th century in terms of structure and writing with the rise of the blockbuster and the emphasis on spectacle, and we lost something after that.
Doesn't the format by itself implicitly change the structure of the content? I know some friends who are in theatre, and even when they do 4 shows a week, there are variations that they make constantly that no two shows are the same.
My musician friends who are scholars in indian music tell me that there is a difference between a written raaga and a performed raaga and in a performed raaga, the actor has the right to improvize on that.
Im trying very hard to not go into the rabbit hole which might become purely academic :) But i would think that if we take how youtube content is structured, or tiktoks are, each format would lend to a new structure.
Thats my sense, i could be wrong. What do you think?
