Hey, it had some interesting ideas, and stands out a lot more compared to other, lesser Dalek stories from the Classic era.  I at least enjoyed the idea of different Dalek factions here, Davros was his usual delight, and overall it was a pair of episodes that generally sat pretty well with me.  Sadly, the final confrontation between Davros and the Doctor, which Resurrection kind of hinges on as the big climax, is pretty underwhelming and didn't really pay off in a meaningful way.  I have mixed feelings on Teagan's departure.  It's kind of nice for this story to feel like it has consequences with the way it leaves her traumatized and kind of done with the adventuring, but again, the execution was a little lacking.  On the other hand, making these two longer episodes did make for a strong sense of pacing compared that worked in a way a lot of the classic series was unable to do.  By not having to break up the story into four breaks, it means that there are less awkward cliffhangers and silly looks we hold on in between episodes that otherwise kind of plague the original show.

It's not perfect - far from it, in fact - but it's a good example of the last few Fifth Doctor stories taking on a bit of life and leaving a much strong impression than what I found otherwise in Season 21.
