Well, I'm way too obsessed with time loops and causality to have had a *best episode ever* reaction on first viewing, but even that kind of worked, because we were seeing it from Sally's linear perspective of time as opposed to the Doctor's twisty turny one where you plan out the effect before the cause. I was however quite jumpy and blinked an awful lot so it defiantly got into my head.

Oh and I adore Sally, she'd make an awesome companion, or we could just watch her non-emo adventures on the slow path.
