Watched this as part of the Doctor Who Day watch-along, and it was better than I remembered. It's a lightning-quick script, but has great performances, as well as being a stinging sci-fi satire against capitalism, warfare, and religion. Ncuti Gatwa is pushed hard being stuck in one place all episode, and his explosion of joy when Villengard is defeated is beautiful. I think this will be one we remember when we look back on his time as the Doctor.
