The Zygons again, then.
There are a number of classic Who villains of whom I have never seen what the fuss was about. The Cybermen are one. Given how clunky the buggers are, you’d think you could escape them by simply walking at a brisk pace. Or failing that, by sprinkling some water over them and waiting for them to rust.
The Zygons are in a similar camp for me. I get that shapeshifting aliens are scary, but it sort of spoils it when they have to keep the person alive in order to remain them. Or maybe I was spoiled by Star Trek: Deep Space Nine.
Anyway, series nine has been on a bit of a roll so far, so let’s see if they can repeat it with the Zygons, shall we?
