I keep saying that to every episode, lately ... :D
From the new series, tennant is my favorite doctor and when I first heard about Capaldi, I was a bit wary. But this darker character adds spice to the story and reminds me of the older series. I like how every doctor is different and how clara deals with these essential changes from smith to capaldi. And how *she* changes because of that.
So who do you think is Missy? :D
