I think it (and the 8 shapes concept) can rather deepen awareness of the complexity of storytelling by giving us a roadmap to recognize and appreciate the nuances of a skilled execution (how did the teller hide the features of the trope? How did they misdirect us? How did they approach the features in a new way?). Emotional responses to art are predicated on expectations either met or contradicted; more understanding of the structures of a medium leads to more active expectation (especially thanks to the generation of a common language with the artist) which can provide more gratifying depth of emotional response.
