Christmas specials don’t count. Intermediate trilogies where David Tennant is the Fourteenth-and-a-Half Doctor or whatever don’t count. The new era of Doctor Who, with Russell T Davies back as the showrunner and Ncuti Gatwa as the Doctor, only really begins here, with the new season proper. The first double bill, comprising Space Babies and The Devil’s Chord, points to a stellar future for Who as a youthfully chaotic playground of the imagination, far more fancy of foot and light of outlook than it has been for years. It only takes baby steps, for now, towards that new destination, but we can see it.
