Arachnids in the UK (2018) is both a homage to the tropes and history of the giant spider movie, and one of the most direct political satires in the history of Doctor Who, looking to comment on and criticise the inescapable personality of Donald Trump at the dawn of a new era for the show. Looking at the philosophy of B-movies, the Gothic sensibilities of the Chris Chibnall era and industrial history, this book offers a coherent reading of this episode’s ideological web: its aesthetic successes, its political failings, and its surprising sociological relevance.
