Peter Capaldi's Doctor Who - unpredictable, embattled, mercurial - has raised many fresh issues for followers of the Time Lord. In this book, the first to address the Capaldi era in depth, international experts on the show explore Capaldi's portrayal of the Doctor, and Steven Moffat's role as show writer and executive producer. They evaluate the effect of Capaldi's older age on the series' pace and themes; his Scottishness and representations of Scotland in Doctor Who's history, and the roles of the Doctor's female companions, particularly Clara Oswald as played by Jenna Coleman. The politics of war are addressed, as is the development of the alien-fighting military organisation UNIT in the show, as well as controversial portrayals of the afterlife and of immortality. There's discussion of promotional discourses, the imagining of the Twelfth Doctor in fan fiction and fan art, fan responses to the re-gendering of the Master as female, and of Christmas television and the uncanny. For fans, scholars and students alike, this book is a fitting tribute to and assessment of Peter Capaldi's Doctor Who.
