Dystopia is a fictional community or society that is undesirable or frightening. It is often treated as an antonym of utopia
a term that was coined by Sir Thomas More and figures as the title of his best known work, a book, published in 1516, which created a blueprint for an ideal society with minimal crime, violence, and poverty.
Dystopias are often characterized by dehumanization, tyrannical governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society.
Dystopian societies appear in many fictional works and artistic representations, particularly in stories set in the future. I like to watch dystopian films, especially science fiction ones.
