His answer to me suggests that he has no interest in Doctor Who whatsoever. Most actors will usually give gushing praise of a show they were on even if the praise is not sincere. Eccleston is completely apathetic, basically has a "I don't care" response to every question. I don't think he likes Doctor Who at all.
Yep, that's the way I interpreted his answers as well. He was very polite and professional and gave answers insightful of his position as an actor. But the content of his Who-related answers leaves me with the impression that something has badly soured him on Doctor Who
as a concept. I'm slowly falling into the camp that we shall never see him reprise the role ... and that's disappointing.
