“It's hard to talk about the importance of an imaginary hero. But heroes ARE important: Heroes tell us something about ourselves.
History tells us who we used to be, documentaries tell us who we are now; but heroes tell us who we WANT to be.
And a lot of our heroes depress me.
But 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 box 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 when we don't need a hero like the Doctor.”
