Reveals how Doctor Who is at its strongest when it reflects the political and cultural concerns of a mass British audience (as in the 1960s, 1970s and 21st century), and at its weakest when catering to a narrow, fan-based audience (as in the 1980s). Chapters range from discussions of the cultural and political relevance of Doctor Who monsters like the Daleks and the Cybermen, through to the show's treatment of themes like energy and the environment in the 1970s.
