I shall try to do this series justice, but would mainly like to reiterate that if you *can* refrain from sharing an unconstructive negative opinion, then please do so. Out of courtesy if nothing else.
I know Moffat himself holds this episode in low regard among his creations, but I'm a little surprised by that, since I've always quite enjoyed it. The "protest or forget" is a great idea, as is the getting Amy to actually use it, because that makes it feel more believable that the population of the ship would do the same. But to me the best parts of it are Sophie Okonedo and the design of the Smilers, both of whom/which are excellent. Underrated, IMO.
