This episode did nothing for me. Earlier (before seeing it) I commented the plot just seemed like someone saying "look at us we can watch the news" which I made in response to the plot centering around a location which is a hot spot with a heavy military presence from the Americans, Chinese, and Russians. I feared this was going to be another heavy-handed analysis of current events which oversimplified what are very complex issues, much like season 9's Islamophobia parable with the Zygons. Thankfully the political side was severely downplayed, unfortunately the episode just wasn't that good.
For the most part, the episode was just there, not really striking any strong reactions either way. If anything, it's the end that just irritates me so much. As far as I'm concerned, Bill's "consent" still originates from fear. And furthermore, it doesn't even follow what was previously established. The Monks said humanity would consent to being conquered to save itself. But by the time Bill consented, the crisis was averted. That is, the Doctor sealed off the lab and had set the timer on the incinerator which would destroy the virus. Bill consented humanity to be conquered to save the Doctor, not humanity.
I got to say, this story arc really is not living up to the hype, and that's taking into account the hype was mostly just Moffat hyperbole to begin with. Part 1 was just a simulation within an alien holodeck, Part 2 felt like filler, and Part 3 looks like it'll be a re-tread of Last of the Time Lords, and I'm pretty certain this is going to end with a reset button of some sort. Hell, with five characters in this episode killed permanently, that's awfully bloody for an episode written or even co-written by Moffat. That alone leads me to believe this will get negated when all is said and done.
