Well, it was an okay episode, I guess. Not much really happened, though. Still, I did enjoy the scenes between the Doctor and Davros, as they do kind of offer some insight into Davros. Yes, Davros was manipulating the Doctor to feel sympathy for him, but that still doesn't rule out the possibility that some of the stuff like Davros feeling lonely and missing his people would be true. In fact, it would have to be in order to suck the Doctor in. The stuff with Clara and Missy was also great, though mainly for the amusement value. And it sure was nice of Missy, tying Clara up and hanging her upside down to zip up her jacket for her. You know, don't want her getting cold now, do we?
The whole thing with Clara inside the Dalek really didn't make much sense to me. We've seen Daleks out of their armour before, and have heard them talk, their voices sound the same. So Clara's dialogue being converted by the armour to sound like Nick Briggs makes no sense at all. Also, we've hear Daleks say some very unusual things even while in their armour. Hell, back in Asylum Oswin Oswald was able to identify herself as Oswin and as a human without much problem, so this whole thing of every attempt to identify her self coming out as "I am a Dalek" or every other attempt at communication being "Exterminate!" just doesn't work.
Also, why is it such a significant plot point that a Dalek can say mercy? This too has already been done, in The Big Bang the Stone Dalek begged River for mercy.
So, I see they're doing an Anthony Ainley thing with Missey being left in situations of certain death but surviving somehow.
Some of the Davros stuff revealed in this episode is odd. So, he really is a torso without legs at all? And his eyes work fine, he's just been keeping them closed all this time? And I couldn't help but be reminded of the Borg Queen upon seeing that cybernetic spinal chord hanging out of his body.
And now, with the Doctor's confession and the hidden true reason for why he ran from Gallifrey apparently going to be a thing for the season, it really does seem Moffat is this time going for something like the Cartmel Master Plan.
