My favorite Doctor is all the ones I've seen. I've seen some of the classic 1, 2, and 3. But I grow up with the 4th Tom Baker. Later I was Reunited with the Doctor with the 9th. I've been watching it ever since.
I have watched the last 3 Doctors. They are all really good actors and each one has brought so much to the show. My mission is to start back from the beginning, when the show first started:)
