I don't really see a lot of people talk about the Hurt serials that ran from '01 to '05. I really felt that the show took on a much darker tone during this period and I'm really shocked at some of the things that the guy we're supposed to call "The Doctor" did. I mean -- the Time War? It made for one hell of a season finale and my favorite regeneration scene ever, but wow. I had a hard time looking at him the same way afterwards.
I'm looking forward to seeing Hurt return in the 50th Anniversary special and I'm glad to see that Smith's Doctor doesn't even consider him to officially be a 'true' Doctor.
