An intriguing set up with clever ideas falls flat as soon as Me enters the story. The momentum of the story relies on the audience looking forward to seeing Ashilder back and Maisie Williams having enough charisma in the bank as an antagonist, but for me she is a limp baddie.

The pairing of Rigsy (“local knowledge!”) Clara and The Doctor is a real treat though. I wish I could have seen a bit more of them outside of the contexts that didn’t work. Rigsy made for an excellent recurring character.

The way that trap street worked and how the masked aliens behaved didn’t always make sense to me. Why is a friendly Cyberman being repaired by an Ood? Some of the pairings didn’t quite ring true.

While Clara’s exit, and the exact rules around how the raven works is a bit contrived, the emotional beats really work and there are some powerful scenes between The Doctor and his companion.
