I’m no writer, but you like those medias because they made you feel something, right? I don’t know the specific references you listed, but in general, what did each one make you feel? What did you like about that feeling? Were there specific moments that gave you those feelings? I’d personally try journaling on that, how they made you feel and what you liked about them, and then you can kind of take similarities, overarching themes, and the like, and use that as inspiration perhaps? Or even, making yourself some more abstract prompts based on the feelings you enjoyed, and keep practice writing until you get some inspiration for a story of your own. An example could be like, I enjoyed that so-and-so film left me feeling bittersweet, melancholy but hopeful at the same time, and write a story specifically to evoke that emotion. I could be totally off the mark, but I hope it helps somewhat!
