What the Heck Does The Great Gatsby Mean?

I personally loved The Great Gatsby, but after reading all the different viewpoints in class, I got really confused. After hearing what all those different groups of people thought the book meant, I found myself wondering, what did Fitzgerald want it to mean? Every work of literature can have multiple purposes or themes depending on what the reader takes from it. I suppose the only time there is a right answer to the purpose of a book is when the author shares his or her intended purpose. In the case of The Great Gatsby, we will never know exactly what Fitzgerald had in mind. Did he mean to demonstrate that the world of his book wasn't real due to the lack of African Americans, as the African American view point says? Or was Fitzgerald just a racist? Is Nick gay? Do all the characters really have a fear of intimacy? These are questions that can only be answered in opinion. with the movie coming out in the summer (which I can't wait to see!!), I'm starting to wonder what interpretation the director will take. Regardless of what people think of the book, I'm sure the movie will have a clear message. Will it be that money is corruption, or that the past is the past and it can't be brought back? Will the movie portray Gatsby as a hero or a crazy, delusional man who chases a dream so far that he falls off a cliff? With so many interpretations of the book, it will be interesting to see what the producers of the movie decide is the "correct interpretation".
