Antiutopia is a term used to describe a society or state that is undesirable or frightening. It is the opposite of utopia, which is an ideal society. The term 'dystopia' is often used interchangeably with antiutopia, as it is a society in which the conditions of life are extremely bad due to deprivation, oppression, or terror. Dystopia is a common theme in literature, film, and other media, and is often used to explore social and political issues.
