Russell T Davies interview in SFX

BBC - Doctor Who - Russell review

"Expect the 'same old mix' of stories for Series 2, some darker, some lighter. Some traditional – although if anything, the traditional stories are BBC Drama's least favourite, but I love them, so I'm gonna keep them in there."

He also says....

"To be blunt, this show is a success, and it's our job to maintain that success, not wander away from it."

Nice. I'm glad that someone as knowledgable/talented as Mr. Davies is in charge (of the stories at leats).
