King Lear
It really feels like this is the film that remains when all else is gone. I see it as exploring the dialectics of art.
art and non-art form incomprehensible madness, where
People just act out of obligation. Soup is consumed because soup is there to be consumed. (hence the lack of manners to the soup-consuming). Writing is done because it can be done. There's no end goal or purpose to anything
furthermore, The "statement" of King Lear is that, even in the absence of art and culture, even whilst everyone is acting out of obligation to the past, with little thought or regard, when the means to create are present, humanity will use them. art and sense will return.
