Hero's are important, heroes tell us something about ourselves. History books tell us who we want to be, documentaries tell us who we are now, 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 call 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.
