Just to be clear, I'm not a writer. That said, there are certain structural elements one expects to see in a well-crafted story... the same way you expect to see certain things in a good program.
Not that I entirely disagree with you, but I think it's more analogous to say that Hollywood is in the business of making burgers. You expect certain structural elements in burgers: buns, centre, sauce. They're incredibly popular for a reason.
The problem comes when we say burgers are basically the superset of decent or nutritious cooking.
