This collection of fresh essays addresses a broad range of topics in the BBC science fiction television series Doctor Who, both old (1963-1989) and new (2005-present). The book begins with the fan: There are essays on how the show is viewed and identified with, fan interactions with each other, reactions to changes, the wilderness years when it wasn't in production. Essays then look at the ways in which the stories are told (e.g., their timeliness, their use of time travel as a device, etc.). After discussing the stories and devices and themes, the essays turn to looking at the Doctor's female companions and how they evolve, are used, and changed by their journey with the Doctor.
