Black Mirror is an instance of speculative fiction within science fiction. The majority of episodes are set in dystopian near-futures with novel technologies that exaggerate a trait from contemporary culture, often the internet. Recurring themes throughout Black Mirror include data privacy and surveillance, virtual reality, individualism and consumerism. Some critics believed that episodes produced under Channel 4 had a more British tone or shared aesthetic qualities not found in later series.
