Some people really responded to this one but I found it pretty clunky, and hard to connect with, to be honest.  It's a bit of a curiosity more than anything.  I can appreciate how grim the whole episode feels but I also can't say I was very invested in my watch experience compared to the average Doctor Who story.  I think part of it is that the Daleks aren't really enough connective tissue to feel like a Doctor Who story.  It reminds me a bit of the Dalek Empire Big Finish audios which I have also been struggling with.
