OK, lets leave Ereth's thread alone. My take: Eccleston was a good reboot, and set a great tone. He was good at conveying an underlying menace that the Doctor possesses, and he had a sense of humor. I think he failed a little with seeming smart even when acting silly, though. I liked his take, but he just pointed the gun in the right direction for Tenant and then Smith. Tenant: He was great at playing up the whimsy and intelligence of the Doctor, but not so much with the power and menace under the surface. He was also great at showing how much the Doctor cares. Smith: different than Tenant, but also great. I think he hit the mark with the Doctor's whimsy, intelligence, and menace. He also looked a little alien to me. Tenant and Smith are tied, IMO. If I watch a lot of Smith episodes, he's my favorite, but if I watch a lot of Tenant episodes, then he's my favorite.
