I was looking at a Doctor Who forum at one point after I’d finished watching the fifth series. There was this person who wrote: “Is it just me, or does Matt Smith’s face look like a foot?” And I just couldn’t help but agree once I read it, because, well, you’ve got to admit that it kind of does. I like him all the same, but it was just one of those things that’s in your brain already but it just hasn’t shown itself to you.
