Young SJ causes a very arched eyebrow and puzzled expression when I watched the Five Doctors (one of the few old Who ep's I've seen). I think that's because I was all pumped for how awesome I was told she was.

I remember reading (I think it was on doctorwho here on LJ) someone saying the same thing. How they just watched some eps with SJ in it and couldn't understand how fantastic she was. Nostagia is a very clouded thing.

I agree I much perfer mature SJ.
