My favorite Doctor is Ten and my favorite companion is Donna Noble. I have yet to watch the classic series thought
Donna, as she was quite down to earth in comparison to the other "over the top" companions. As for the doctor, I'm torn between Christopher Eccleston and David Tennant. Matt Smith while likable, was a bit too goofy and Capaldi, well... the whole "old doctor" didn't "click" with me. He was far too "different".
I'm really fond of Ten and Four.. My favorite companions are Sarah Jane Smith, Donna Noble, and Jamie McCrimmon
Donna Noble! she was brilliant. Ecky, ehem i mean Eccleston was my favorite Doctor but I love Ten and rose a lot. Series 1 and Series four are my favorites. I would rather watch love and mosters and fear her on a loop than watch some steven moffat episodes tbh, i'm definitely an rtd fan.
