You can see what Jarmusch is up to. He is making the effort, which few movies have even attempted, to dramatize the act of poetic composition, to suggest what manner of struggle, or reverie, or self-surrender, is entailed. I don’t think his plan succeeds (nor can I really imagine what success would look like)…
