Wow...okay.... that's going to divide the fandom! A truly astounding piece of television, so gripping, action-packed and utterly game-changing. The Doctor is back to being a fully mysterious figure again, we don't even know her species any more!

My only criticism is the same as last week: Captain Jack should have been there. He was clearly heavily linked to the Lone Cyberman arc, and his absence makes literally no sense. How did Chibnall not think at any point during writing process 'Hang on, I need Jack'?

That cliffhanger though...bloody hell, how is the Doctor going to get out of that? And how are the fam going to cope without her? It feels like watching the RTD era all over again!
