Torchwood was at that point still at the jumping up and down going: 'Look! Look! I'm all adult and violent and grim and full of sexual content!!!' stage. And I guess nothing symbolises that more than the sexy cyborg...

You'd think they could have been more interesting with the design. And when I say 'interesting', I mean 'horrific, grotesque body horror'. XD Re-reading all this makes me wonder if this episode was on Moff's mind when he wrote Dark Water/Death in Heaven and put Danny as that half-converted Cyberman. There's nothing sexy about Danny there, it's pure horror and tragedy.

I would also prefer crack over Miracle Day and the evil space vagina.
