LOL! I haven't seen it and am avoiding spoilers...but you should see my correspondence list on this episode.

1. Infruriating, I need a protest button
2. Amazon Satire meets Middle Dicksonian twist and not in a good way
3. Amusing work satire until you end up with ridiculous right-wing ending

And then..."this is my favorite plot of the whole season so far?"

I'm guessing it is a wee bit controversial for a Doctor Who episode?
