Starting to a get bit bored of this structure of bouncing between Liv and Molly and there's a big overarching plan with the Eminence, Time Lords, you know the drill. A scorpion race who has issues with humans, their voices were very cool but nothing was entirely what we have seen before. The Doctor going to restart the whole timeline though? That's fun. If you didn't know Narvin, you'd definitely think he was evil. Really this is 3/5 and not 3.5/5 because precious little Macqueen Master.
