I think it's largely that you haven't seen the other five seasons. You should get on that! I gave you a list of the best ones and everything! :)

Nine was all traumatized and angry, and Ten was a bit more put together, but Tennant could still do a pretty good "coldly furious" when called upon.

Or, actually, let me put it another way: are you actually fully aware of exactly what HAPPENED to the Time Lords?
