My favourite 13th Doctor episode. She is brilliant here. I love her interactions with the Lone Cyberman, the speech about the not so flat team structure when there's real danger, and her losing in the end in order to save one life. Plus the horror vibes are on point. One of the best in all of New Who.

Decent episode, not a fan of "haunted" house stories, but glad it had a scifi explanation to it.

I have to admit, I don't really get the love for this one. It's a really solid episode, delightfully creepy with great atmosphere and set design, but that's pretty much where my praise for it ends.

The Lone Cyberman was hyped up quite a bit, but I don't really get his deal. If I remember later episodes correctly, he isn't even properly utilised in them. A Cyberman without an emotional inhibitor is an interesting idea, but I don't think it's done well here.

I feel like, for being the most famous person in the episode, Mary Shelley was sidelined quite a bit. Everyone knows Frankenstein, but I don't think I've ever heard of any of Mr. Shelley's writing. I think the guardian thing would have worked better if it was Mary who was holding the Cyberium, instead, but for all I know they were drawing from real life for the way it effected him.

It was also just a bit slow. A lot of it was building up the tension, sure, but it was a bit too much for my taste.

I do love Thirteen in this episode. She has a few fantastically odd moments, as well as some great speeches, but that's not really unusual.

A celebrity adorer of thirteenth, finally!

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.
