Not so impressive when this one's just the last in a long line. (And what I want out of that scene is what happens *after* the clip ends.)
Yes and yes. (And like I said on doctoreleven, what I really want is for the Doctor to add "Twice" after his line about killing all the Timelords. :)

I have no idea about the rest, but did you notice the shot of an unlit Maldavorium?
YES I DID!!! Eeeeeee! *flails some more*
