So after an amazing series, i believe Matt Smith is becoming my favourite doctor. He is not as manic as David Tennant, but there is some real darkness there and he manages to come across as someone of age, if that makes sense.
I always enjoyed Tennant mind, i just dont think he was given many great stories. It may have been nice to see what kind of doctor he would have made if someone had told him to just reign it in a bit.
