I really don't mean to keep resurrecting old topics, but I honestly have to say:
Elisabeth Sladen hit it out of the park with Sarah Jane's reaction to the Daleks. I've never seen her before New Who, but the absolute, abject terror she exudes is almost palpable. Just standing there, wide eyed and tear stained, shaking in naked fear.
I had to rewind the scene, just to watch it again. Bravo!
