Query: The Many Faces of the Doctor

Being a life long fan of the Doctor, I have can say the newest Doctor really had me questioning the path this character was taking. It wasn't until the season finale that I felt he truly captured the essence of the Doctor. Granted many of the previous persona's he had were more fluid in their conversions, I really feel that the initiation of this new form really clarified for those unsure of what it is like to get a new body for the Doctor. In previous series, it was hinted at but not quite as clear but this series really gave shape to the challenges the Doctor faces when his form changes.I also think this new perspective of the Doctor with a more dark and less empathetic for the human kind has become more like the Master was in the earlier series so I wonder where they are going with this approach. I wonder where we will go next. But you can be sure, I will be right along with him as he goes through these challenges and changes.
