Really? I thought it looked like they'd badly stretched the budget, none of the aliens even had faces that moved. The sets really limited. There were some interesting stuff that didn't really seem to hit properly. And to be honest the whole thing with Clara is grating. What is it with Moffat and the obsession that the companion has to be special, and the Doctor will have known/seen them through various parts of their life? Amy, River (in a round about sort of way), Reinette, now Clara, it's annoying.
