4. "Trust Me For 20 Minutes"
No one was sure that Matt Smith was the right Doctor for the part. If you say you were, you're lying. Most of us agree though that Matt Smith became the Doctor when he uttered those immortal words, "Hello, I'm the Doctor... and basically run". But why that moment? Well, Amy didn't trust the Eleventh Doctor either: she'd had four psychiatrists because of him, and well, maybe she was an Eccleston fan? It was a moment of Eleven asking for her faith, just for him to prove himself, that swayed her though. He was asking us to trust him too, and when we did, he worked his magic, and earned the Atraxi confrontation. Say what you like about Moffat, he's never taken his audience for granted.
