The first thing that strikes me is that the story here is held together by a lot of wild contrivances. Mickey and Jake get to the roof of Battersea undetected...somehow! Despite normally clanking around, the Cybermen can still sneak up on you when convenient! Mickey's hacking skills (granted these have been halfway established in the past) are strong enough that he can find the override code for the emotional inhibitors in a matter of seconds! Also, he knows how to fly a Zeppelin because PlayStation!

With that all the way, I think the emotional core of the episode is strong. The body horror is executed perfectly, with the "why am I cold" scene being absolutely outstanding (and something that I'd forgotten about, shame on me).

I really appreciated Pete's "rejection" of Rose, even after he learns the truth. It's unsatisfying in a very real sort of way.

I'm less fond of Mickey's departure - it's fine, I just don't care much for Mickey. I do think it would have been more resonant if Eccleston was still the Doctor, since he showed more disdain for Mickey last season.

It was nice that the episode spent some time with Jake, and especially Mrs. Moore. It's a little surprising that we never met their counterparts in the mainline universe.

Lastly...the Cybermen could be a good metaphor for toxic masculinity. Maybe it's time to revisit them.
