in my view this be the single best season of Dr. who . I know that be say a lot - and I know a lot of people would disagree with I . it be pointless to say all the story in Series 2 be great - because virtually all Dr. who episode from all the season be great . I think , more than anything else , it be the character of Rose Tyler that put this season over the top . she be great in Series 1 ; but she be almost sublime in Series 2 . plus , this season contain the single most poignant story in the entire Dr. who repetoire . though I agree with Colin Baker , who reportedly say that `` the empty child '' -lrb- from Series 1 -rrb- be just about the best Dr. who episode ; to I `` the Girl in the fireplace '' from Series 2 be the most poignant . it be far from the best Dr. who ; the alien menace be almost comical in the way that some of the alien from the earliest Dr. who episode be ; and the story line do seem stretch a bit . but there be something so almost magical about the episode , and so unexpectedly sad about the end . you get the feeling that if Dr. who could have choose a true soul-mate from among all the woman he have ever encounter , it would have be this `` Girl in the fireplace . '' and the two-part episode `` the Satan pit '' show the depth of the bond between the doctor and Rose more succinctly than any other episode ; he be willing to place he life entirely in she hand - that be how much he be come to trust she instinct for do the right thing . then the season finale , another two-part episode , bring they relationship full circle . it , too , be one of the most poignant Doctor who episode - and one of the most innovative , pit two of the Doctor 's greatest enemy against themselves as well as against the world . all in all , this season be nearly perfect .
