A theory: performances as the Doctor divide into two categories. There are those that seem like extensions of the actor’s own personality and charisma (Pertwee, both Bakers, McCoy, Smith), and those that seem like more orthodox acting performances (Troughton, Davison, McGann). On first glance, I’d put Christopher Eccleston’s 2005 portrayal of the Ninth Doctor in the latter group. But on reflection, I’m not so sure.
