Rose gets in trouble every episode...she has opinions and takes action on them. However I do think she can be a huge idiot sometimes
Yes I like that she is both. Makes her more "beleivable" and easier to identify with. It is hard as a woman (or as a girl as I was then) to identify with the helpless, scream-y, fall over and hurt ankle kind of companion. I think new audiences have a better companion with Rose.
I agree with Promethea. Rose rocked in that last epi and had *gasp* evolved!!!!!
Fadooski asks re Rose's youth.
Ok. I think she is young (I thought she was 19 but there you go) to encourage new young viewers who didnt grow up watching the old doctor so that is why she was cast.
As to the subtext thing which is often complained of by oldfans, I think it's a good thing. Yes I'm a sook and romantic but they do emphasise his loneliness and for me it is nice he finds someone. He is the last TimeLord after all - he can't hang with his own species. He loves humanity for the most part - so what other species is there?!!!
