The way I read it is that “want something” can be just wanting to live your ordinary life. Which will then become at odds with something extraordinary.
Originally, when I was trying to think about stories, the following came to mind
- Revenge movies like John Wick (the first one), and video games like The Last of Us 2, where the protagonist originally just wants to go about his affairs, but bad things happen to them and they want revenge.
- "Catastrophe" movies like Alien, Predator, Terminator 2, where the protagonist needs to act to stay alive
From another commenter I understand that the revenge or will to survive becomes the want. But not sure if it really fits the presented scheme that well anymore.
Which films are you thinking of?
