Davies himself said the primary reason for taking the series in the direction implied by the document was to make things more "epic and emotional". It also allowed new viewers to have a clear jumping-on point. They didn't need to understand the then-forty years of back story of the first eight Doctors. All they needed was the fact that this Doctor — the Ninth Doctor — was the last of his kind. It was, according to Davies, a way to level the playing field between new fans and fans of the classic series.
