I honestly really loved that! Like, a lot!
Cons:
It wasn't perfect, however. Of course. A few little nitpicky things, and one or two bigger complaints:
So, the bad guy was a little too one-note evil capitalist/politician. Some of his lines made me roll my eyes, like "this is a PR nightmare" being his reaction when he learned that the Daleks were eating liquified humans. The irony of him suddenly being hailed as a hero worked okay, but he was maybe just a touch too cartoonish for my personal preference, in an episode that mostly managed to feel really grounded.
Sometimes the Dalek stories will touch on this "race purity" thing, and the Doctor will talk about how they are beings of hate, and it really feels like we're doing a Nazi allegory, but they don't quite... go somewhere with it? Like, we've got the Prime Minster character talking about protecting borders and increasing security, and then the Daleks who are trying to stamp out "impurities," right? And there's something there, it's not exactly the most subtle of story craft, I guess I just wish it felt more intentional. The Daleks have metaphorical resonance here, and I'm not sure it was totally utilized.
