Moffat

       "It's hard to talk about the importance of an imaginary hero. But heroes are important. Heroes tell us something about ourselves. History books tell us who we used to be, documentaries tell us who we are right now but heroes tell us who we want to be. And a lot of our heroes depress me. But you know, when they made this particular hero, they didn't give him a gun, they gave him a screwdriver to fix things. They didn't give him a tank or a warship or an X-wing fighter, they gave him a callbox from which you can call for help. And they didn't give him a superpower or pointy ears or a heat ray. They gave him an extra heart. They gave him two hearts. And that's an extraordinary thing. There will never come a time where we don't need a hero like Doctor Who."
