So many video essays about how to get the 3 act structure right, the Hero's journey, analyzing films through this lens, etc. Dan Harmon is always yapping on about his "story circle"... it's like damn is writing really that bland?

I feel like adherence to these guidelines and the quest to find the perfect structure cheapens things and generally gets in the way of things. But I don't know anything about writing so maybe that's nonsense. What do you guys think?
