We need to talk about Zoey. Zoey is awesome, is crazy smart, sometimes even smarter than the Doctor. She’s great and this is her first story, The Wheel in Space.
The Cybermen are my favorite monster. Sure that might be my Star Trek: The Next Generation roots showing, but the idea of someones humanity and individuality being lost, either by choice or by force, is truly terrifying for me. Granted that’s not showcased in this particular serial. What is, is a basic and formulaic ‘base under siege’ story that is the format for this whole season.
The Cybermen want to invade Earth and the first step in that is to take out the Wheel. So for six episodes they use stealth and subterfuge to try and take over the base and it works pretty well. In this, Zoe’s introduction, she acts more like a walking computer than she does in later stories, but with her addition we get to what is for many the defining TARDIS team for the Second Doctor, if not for the whole show.
