Hello. You forgot to say that this question is about "The Great Gatsby".
Answer and Explanation:
Although "The Great Gatsby" has some romantic elements, I believe that the story goes far beyond that, not allowing me to see it as a romantic and sentimental story. On the contrary, I believe that "The great Gastsby" presents the domination of money, the American dream and the imbalance between the social classes that the country presents. The book shows how all these factors, acting together, interfere in the lives of citizens, in all possible elements, even in love.
