The problem is the Matt Smith Character is vitally important, but Matt Smith was bad stunt casting.
Kind of have to strongly disagree on the Daenerys lite comment though, Daenerys the dreamer, AKA, Daenerys 1.0 saw that everybody in valyria was going to die horribly.
So she convinced the targs to set sail, and the entire saga kicked off.
Daenarys Targaryen, daughter of Aerys II, may has well have been her brother. All that struggle, and then her brain got bent by stupid.
