I am pleased to report that this holds up five years later! The tension is on from just about the beginning of the episode, and it stays exciting throughout. The covering up of one of the most shocking plot twists ever with the Fugitive Doctor by waving Captain Jack at us is so smart. The Jack scenes aren't quite as good as the rest, but it does get the companions out of the way and Jodie Whittaker and Jo Martin have great chemistry together. The tension keeps building and building, and has quite a satisfying resolution with Gat getting killed. Also, we really need to talk more about the Fugitive Doctor being married!
