Idk, I feel like knowing standard story structure is a way to help you get more understanding out of a story. IMO, a good story is predictable in some ways. If knowing the ending takes all the fun out of it, then it probably wasn’t a very good story.
Also: I generally watch for two specific moments in any movie: the “meeting with the goddess” and the “atonement with the father”. Those two scenes really tell you a lot about what the writer cares about and how they think about their characters.
