The allegorical plotlines of the series contain elements of science fiction, psychological drama, and spy fiction. The show was sold as a thriller in the mould of Danger Man, but its surreal and Kafkaesque setting and reflection of concerns of the 1960s counterculture have had a far-reaching influence.
