The sum total of all of this is a really, really good slice of Saturday night fun, that puts a good Dalek story at the heart of an episode that’s impressive for reasons beyond its foes. It’s frequently funny – Moffat hasn’t lost his touch with excellent one-liners – and emotionally involving too. It also takes the Daleks to some quite dark places, with a fresh, unpleasant edge. And, as with many of Moffat’s episodes, it’ll ignite the Internet within seconds of it finishing.

The fiendishly clever script is packed with Moffat’s trademark dazzling wordplay and several guffaw-out-loud gags, while there are two scenes that will have viewers sniffling on their sofas. Best of all, the story makes the Doctor’s pepperpotty arch enemies truly scary again and contains several killer twists.

Elsewhere, the opening credit sequence has been subtly tweaked and although there’s no mention of “timey-wimey”, there is an “explodey-wodey”. Back with a bang indeed.
