Actually I thought the plot was a bit of an unintended nod back to Spearhead from space, but I say that about every episode where the Doctor takes off his clothes in a hospital.

And you forgot the other Moffat trope: Nobody died. Or rather, nobody was killed.

(And yes people did get eaten by the Vashta Narada in the library two-parter. I will concede that if you believe in a soul they are dead, but if you are a secular atheist they are still alive. They are in a sense Schrodinger's Gedeankenexpriment.)
