This one starts SO WELL. Another compelling premise for a Doctor Who episode: what if Daleks tricked the Allied forces into helping them fight alongside them, in the Second World War, only to reveal themselves to be more like the Nazis once it was too late?

For me the story starts to fall apart at the point at which it turns out the Daleks were looking for The Doctor, rather than just doing a dastardly deed in a historic setting. It makes everything revolve around The Doctor in a predictable way.

Then it does the typical Doctor Who thing of devolving into a runaround, which is my least favourite thing about the show. You have Spitfires in space with threadbare, minimal explanation and justification. Then that moves into a ‘power of love’ ending with Professor Bracewell having to remember he is human, and it’s all a bit weak.

Which is such a shame because until the reveal it has so much promise. Ian McNeice’s Churchill is excellent and plays well off The Doctor and Amy.

Mark Gatiss is a very okay writer. The Unquiet Dead is seminal, then The Idiot’s Lantern is perfectly okay, then this continues to be very okay.

I would like to raise a spirited defense of the skittles Daleks though - I think they look neat! I wouldn’t want them to be the standard Dalek design, but the show is richer for their existence.
