Its known as a great American novel or novella as it was kind of short, and I can say that I enjoyed the book more than I imagined. This is the only Fitzgerald book I have read and I was impressed by the lilting nature of his writing style. In such few, but essential words, Fitzgerald created a clear picture of the culture of the 1920s Jazz age. 
 Nick was an ideal narrator as he is a man looking in on the culture of excess he exists in. Its a book about rich people and their problems and while very few can relate to their troubles, Nick begrudgingly explains their problems in a way that at the very least, I understood. Tom and Daisy are both so unlikable as characters, but its okay to read about them because the narrator hates them with you. Gatsby, the mysterious and charming center of the story, is not exactly lovable, but he's written so well his complex nature make you empathize with his plight. He lives his whole life for the hope that Daisy will take him back and love him on his terms. She does not and all of his dreams, all his efforts, and all his goals shatter into nothing. He lived in the past and was unwilling to let go and as a result could not enjoy the life he had built for himself. The book has a sad ending for Gatsby considering the book is called the Great Gatsby. But I suppose that was the point of the book.
