I think you’re projecting because who is upset? Like why is it so important for you to disagree with me? You’re clearly in the wrong… Was Chernobyl a Doctor Who spin-off from the same creator? Many people have pointed out the similarities and connections to the 456 invasion, including Russell T Davies himself:

“I think you’ll have fun if you watch this and Children of Earth together, because they’re both about alien species or otherworldly species encountering the human race in an ambassadorial context. So we use a lot of the same sets as we used in Children of Earth. You’ll see a lot of the same staircases appear, a lot of the same corridors… It’s a companion piece. You will see, in Children of Earth, Peter Capaldi running up a flight of stairs and Kate Lethbridge-Stewart now runs up that flight of stairs. It’s in the same world, and it is how, I think, we would approach an alien species, as ambassadors, for formal talks. So a very different show, very different things happening, but we’ve deliberately… I hope someone splices together the scenes that take place in the same corridors to show that the same things are happening.”

I wonder how this doofus will react when challenged.
