The apocalypse theme serves as a reflection of human society's collective fears and anxieties. It provides a platform for creators to comment on current issues, such as climate change, politics, and social inequality. The apocalypse represents a turning point, where the norms and structures of society are broken down, and individuals are forced to confront their own mortality. This theme also offers a sense of catharsis, allowing audiences to experience and process their emotions in a controlled environment.
