People like to read books about either dystopian or utopian life because they like to see how life would be in a different time, hence books such as Divergent and Hunger Games. As the saying goes, opposites attract. Our civilization is neither perfect nor apocalyptic hence we are attracted to other types of literature. Utopian and dystopian themes are not contemporary making them more appealing to larger crowds. There is nothing wrong with us liking these types of books, it just shows that we are curious and like reading about new stuff. As this theme is not contemporary it can be understood for a longer period of time making it more universal and famous making this type of genre more appreciated then others.
A famous question asked by many others regarding why we are attracted to this unusual genre is: "Does this interest tell others about the way we see life and how we perceive it?"
