I'm not sure the BBC could pay them enough to come back, especially since Amazon is paying them tens of millions to do a few specials a year. The BBC was right morally to fire Clarkson, but they were absolutely idiots for firing Clarkson, since they tanked one of their most popular long running shows to make a point by doing so.

The Doctor is a fearsome creature, as seen at the end of Family of Blood. Even the most fearsome races, including the Daleks, fear him, and for good reason. He can be civil, polite, and even cheerful and jovial, but he is not a nice "person".

One of my favorite moments is when Matt Smith has an alien race look up what happened to every race that opposed him and then tells them to run.
