2. Roses Character Development
At the beginning of series one, she was your average kind of human being - a nineteen year old girl working in a shop and living at home with her mother. Nobody really saw anything particularly remarkable within her - until the Doctor turned up. The Doctor showed Rose how much of an impact she - and every other human being on the planet - could make throughout all of time and space. By the end of the series, this girl absorbed the power of the time vortex AND LIVED, but not before she had faced up to the Daleks, conferred with a tree of Cheem, helped to save the entire planet from destruction at the hands of the Slitheen and even talked the Doctor himself out of killing a Dalek. She helped the Doctor to become a better person just as much as he helped her. And while many of us watching the show will most probably never see far off galaxies or alien species as Rose did, her character development was sort of symbolic to us - because she was an average person, we could really relate to her. Rose helped us to believe that perhaps, just maybe, we too could do things that were truly fantastic.
