“Question – why do we talk out loud when we know we’re alone? Conjecture – because we know we’re not.”
(SPOILER WARNING!)
After last week’s love-it-or-loathe-it comedy episode, this week saw Doctor Who back on more familiar ground with an outright horror story. The show’s always traded on an ability to scare small children, and in the post-2005 run, arguably nobody’s been better at that than Steven Moffat. Before he became showrunner (and subject to vitriolic brickbats from those who disliked his style), his episodes for Russell T Davies traded on being ‘the scary ones’ – The Empty Child, Blink, even Girl in the Fireplace, with its organ-harvesting clockwork droids that hid under children’s beds.
