I feel like we definitely got the more nuanced Moffat. While not his best effort, the story was nonetheless wonderfully intense as we watched The Doctor's attempts to remain calm while standing on a live landmine. Not just any landmine but one that utilized its victims bodily energy on a quantum level to create the explosion (assuming I remembered what was described correctly)...which is bad for everyone on Kastarion 3 when that victim is a Time Lord. I really enjoyed each instance that The Doctor had to deal with while staying practically still (as Moffat had noted before, he removed The Doctor's ability to run...and his ability to get people to listen to him when he told them to run!).
I was fascinated by the existence of Villengard, a corporation that profited solely on the continuing existence of casualties of war to the point of fabricating a war. I didn't expect it to happen in this episode based on the brief preview focused on the landmine, but I loved how Moffat has once again taken an ordinary object and made it genuinely scary: In this case, an ambulance in the field of combat, one that decides that even if you can recover from temporary blindness, you might as well die if it's not fast enough. While not nearly as gross as the snot monster, the canisters of its victims' bodies were pretty damn creepy.
Considering we know that Susan Twist appears in more episodes, I hope this means we haven't seen the last of Villengard because I am curious to learn more about them and explore that particularly awful aspect of capitalism and greed.
As speculated, we did indeed get the return of the Church of the Papal Mainframe, but I was disappointed that we didn't get to learn more about them aside their current conflict. I still think they're a neat idea to explore and hopefully they'll also return when Villengard inevitably returns, too.
Lastly, I loved seeing Varada Sethu from Andor pop up in this episode. I knew I recognized her right away but I couldn't place her until after the episode, upon realizing that we already knew she was going to appear as the next companion...although I'm not sure if we knew was going to appear for the first time this season. Either way, I'm looking forward to seeing Mundy again.
