I think the 2013 movie unfortunately has made the book into the symbol of the roaring 1920s era, and that comes with a lot of baggage that Fitzgerald didn’t intend to put center stage. I can’t think of any other mainstream media that is also set in the 20s and has as big of a cultural pull. So everything 1920s related gets crammed into Gatsby, when in reality it’s more of a fable on American identity.
