However, watching it now, with everything I know about Narcissism, was like looking at the story under an entirely new angle. The whole story is about Narcissistic people who are so self-absorbed, they fail to see the reality about those around them.
The conversation between the owner of the petrol station and the neighbour who is "trying" to console him, is a classic dialogue of two people not "hearing" each other. There are many other examples throughout the film.
There seems to be a lot division of opinion over whether "The Great Gatsby" is a good book or not, and from what I read, (after I watched the film and deciding to do a bit of research,) a lot of people don't like the story because they don't like the characters. As I read their comments, I thought: "But that's the whole point: you're not meant to like them". This story, whether F. Scott Fitzgerald meant it as such or not, is a cautionary tale. It should come with the following warning on the front of the book (or the film, for that matter):
"This is a story about careless people who "smash up things and creatures and then retreat back into their money or their vast carelessness or whatever it is that keeps them together, and let other people clean up the mess they make.” You will encounter people like this too, so pay attention, and when you do encounter them, don't let them come into your life."
