Genuinely one of the best stories in Doctor Who history, it is intriguing, surprising, well-written and acted throughout, with a gripping story and a whole new, beautifully established world that is fully explored.
The idea of showing a story is set in a surveillance state by having literally every scene take place on a monitor, is completely genius.
It is a master class in world-building and exposition writing, it never, and I mean never, spoon-feeds you exposition by having someone explain something to a fish-out-of-water character, every piece of exposition is something that that character would say in the scenario, and yet still it manages to fully build-up a completely new world with a bucket-load of new concepts and ideas that are completely foreign to us, explained most of the time to us eventually, but most of the time you have to think about the implications to truly understand what is going on, it is begging you, demanding of you that you engage with it to understand the world it is building up, and it deserves that of us.
And to top it all off, the sound design and mixing are truly beautiful, it reminds me of certain experimental arthouse movies that utilize sound as a non-verbal story-telling medium and it just works so incredibly well.
I hope someday this gets adapted into either a standalone or a Doctor Who movie or 2-parter, it works perfectly in audio, but I also wanna see it in visual.
I will be listening to this story for the rest of my life.
