Which theory about identity construction helps explain the effect the narrative had on you or its audience in general

During the term, you learned several different theories relating to both identity and popular culture. For example, you learned about the following:

how we construct our own identities,
how we interact with popular culture phenomena,
how pop culture phenomena help us define our humanity,
how the narratives we choose to engage with affect how we tell the narratives of our own lives, and
how the medium through which each narrative is told affects how we understand it and engage with it.
For your Essay, you are required to analyze a popular culture phenomenon of your choosing, using two or more of the elements listed above. Pick a narrative that engages you, something that has made you feel differently about yourself or given you a new insight into what it means to be human.
Once you have chosen a narrative, consider the following:

Which theory about identity construction helps explain the effect the narrative had on you or its audience in general;
the medium through which the narrative is experienced and what effect it had on you and/or its audience;
the characters or protagonists included in the narrative—how do they relate to our definition of what is human?
if anything else about the narrative affected your perception of humanity or your identity (if so, explain that as well).
A discussion about identity construction plus two or three other interesting observations about the characters or the medium will form the main body paragraphs of your essay. Your thesis statement can be quite simple, along the lines of “[Chosen narrative] demonstrates identity construction because it makes us think about _________ using the medium of _________.]” That is just one way of organizing ideas. You are free to be more creative and make your thesis fit the things you want to say about your chosen narrative. You can adapt the content of your paper to suit your narrative as long as you don’t ignore the idea of identity or the effect of the medium (film, book, game, etc.).
Support your observations with specific references to the relevant articles on identity construction, media effect, and your narrative of choice.
