It’s been a rather great run of Doctor Who episodes this year, but unfortunately all good things must eventually come to an end. And that end is nigh, as we reach the penultimate episode of series/season nine – Heaven Sent. Written by Steven Moffat and directed by Rachel Talalay (who previously directed last year’s finale two-parter Dark Water and Death in Heaven), this episode is a particularly interesting case as the only speaking role is the Doctor himself. With no other actors to bounce off of this episode is truly the Peter Capaldi show, and as the Doctor quite rightly says to himself here “the room is yours, so work it.”
