Okay, I'm fully around on Alex Macqueen's Master now. I love how smug and sarcastic he is. So over the top. This story is more about him than the Doctor, and he shines.

A. Maybe B.

Been really enjoying the Master in this set, he's exactly like what I'd imagine the Master would sound like.

Leagues better than the previous two parts. Earth has been taken over by the Daleks, human resources have been depleted so now they are tempting Sontarans to the planet for conversion. The master is working with them of course. Having an older Molly makes narrative sense and a an acceptable workaround for not being able to get the real deal. It is fantastic seeing the master's plan come together - he takes over a Dalek army! The way he betrays the Dalek leadership is very satisfying and MacQueen's performance is once again, perfect.

kinda drags a lot this one, just felt like it was filler really before the big conclusion! some nice scenes with the master, and the totally surprising (/j) return of molly!
