Darn, I can't link you an extended scene yet that really drives Matt Smith's Doctor home. I assume it was cut for time, but goddamn it sucks that it was cut.
Eccleston was better than either of them anyway.
You know, i've only seen one matt smith episode. It was a christmas episode, and he was depressed as fuck. And he called some guy a potato. That's all I got from the episode. Depressed and likes calling someone a potato.
