It's not terrible. And it's better than some of Series 11. The Recon Dalek is actually quite good and manages to be more threatening than past Daleks. No matter how sound the plot might be, it's really quite uninvolving. Yaz, the best of the 'fam', is once again left in the background. This episode also contains one of the most un-Doctor-Whoey scenes in the show's history. If you walked in at that moment and told me get Corrie off the screen, I wouldn't be surprised. Still, at least Chibnall is a remainer.
