Even tough i did not quite like the tenth planet and the Mondasian Cyberman and i was really worried about their return this turned out really well. It was a great acted episode and also like all of the other Moffat stories really well written. I hope Bill will stay gone because i don't like her but i like the other characters. The only thing that annoys me about this episode is that the BBC spoiled the return of John Simm's Master if they won't have done this the reveal would be way better so BBC PLEASE STOP SPOILING. All in all this was another Moffat masterpiece
