A lot of criticism is leveled at Rose's character, but I remember this part and I feel like if saving the world twice is not enough... oh well. Can't win them all.

I guess not. Heh.

Also. For some reason, Doomsday makes me think of the Ninth Doctor, a lot. I'm not sure why.

Maybe because a lot of S1 (and Nine) is dealing with the Time War - guilt, loss? And in Doomsday, that Rose band-aid for that was ripped off, and everything's sort of reset to when we first met Nine.
