Which is not exactly true, because when they move, which this is very stupid, they are still just moving statues. So anything you think is scary about them, no longer scary. And the only reason they're here at all, in a story that manages to strip out all the least interesting bits of the Vashta Nerada and present them as something new, is because somebody bought Moffat a drink or something and gave him props on the Weeping Angels, and instead of thinking about what was actually cool about that story, decided that the Weeping Angels -- and no doubt the merchandising opportunities they present -- were themselves what made "Blink" cool. Which, it's one thing to misunderstand what works in somebody else's story, and twist it, but how fucked up is it that you could take your own awesome story and stripmine it like you'd never even seen it before?

But then the Doctor says this is "the ultimate defense mechanism," and it's Amy that says, "What, being a stone?" Which I can't help but think works on two levels, since that's what she did. (Echoes of Jackie's "we get hard," in the Elton episode, which was it turned out less about getting blowjobs from concrete and more about what happens when you lose Bliss in pursuit of the Doctor. Elton is an Amelia that never became an Amy; he was saved from that fate or became something worse, depending on your point of view.) "Until you turn your back," he nods.

Problem one: Since the hyperdrive split on impact, the whole thing is racked with radiation and "gravity storms." Deadly to everybody but Angels, who love that sort of thing. Quick Excellent rundown of the indigenous two-headed Aplans, who died out 400 years ago, and then 200 years later, humans terraformed and built up their numbers to six billion. What part of this information is necessary? None, and given what happens later actually it runs counter to the plot, but at least it's an excuse for yet another "You lot, you're everywhere! Like rabbits! I'll never get done saving you!" joke, because those go over so well.

The Doctor tells the Bishop to lock and load, he calls out to his Verger about the explosives -- which is just brilliant, of all the different clerical words they use here, because of what a verger does -- and Bishop Octavian summons River Song in turn, but she calls out, "Two minutes! Sweetie, I need you!" The Doctor follows her, and Amy feels left out. She heads inside the communications room with the Angel video, and it's taken its hands from its face; it's beginning to turn toward her.
