There is no other word for that episode than utterly fantastic. I loved the spooky haunted house vibe, the stuff with the constantly changing house and Ashad The Lone Cyberman. Its design is impeccable, and the Cyberman  having no emotional inhibitor is  unique.

Jodie Whittaker's speech about sometimes not always being able to win and not wanting to lose someone else to the Cyber-conversion is going to go down in Who history as one of the all-time greats. Yet another instant classic after three already in one series.
