Jamie does all he can to stop the Wheel from destroying the rocket holding The TARDIS, but his act of sabotage allows The Cybermen to gain access.
Of the first three episodes, in glad this is the one that exists, as opposed to the other two, not much happens in either, however this one has more content. We get to see The Cybermats, we see the first meeting between The Doctor and Zoe, plus we get to see more of The Cybermen.
Often six part serials slow down in the middle, this one has improved as it's developed. I'm not sure about those Cyber voices here.
Wendy Padbury is effortless, she looks so at ease with Pat and Fraser, talk about perfect casting.
Always good to see Kevork Malikyan, who plays Kemel, not a big part, but interesting to see him in his youth.
It's pretty good, 7/10.
