Well, that was about as bad as I remembered. Like all of the many Doctor Who stories that fumble, this one has a couple of neat concepts in it. This one should feature the remarkably interesting idea of a living city, but because this is just Who by the numbers, the city is just a location for a deeply boring and slow chase with Daleks somewhere behind them. The “Pop Goes the Weasel” / “Three Blind Mice” music emphasizes just how slow and stodgy this is.
It’s never interesting, and never even fails in an entertaining way. I’m reminded of how “The Claws of Axos” looked and felt so shoddy and rushed. This doesn’t have any of that story’s weird editing decisions or poor acting, but it also doesn’t have that story’s sense of doing something weird, new, and unique. “The Claws of Axos” tried to be different. This just tries to be the same Dalek adventure that they did the previous season.
Mercifully, the Dalek adventure in the next season would try to be something entirely different!
