Tom Baker era producer Philip Hinchcliffe speaks in the current published issue of The Stage about his feelings on modern Doctor Who.
He speaks about a number of developments in the shows format, for instance story length:
"The structure of these single episode stories is interesting," Hinchcliffe comments, pausing the DVD for a moment. "It’s flipping the familiar sci-fi idea of a people enslaved. Here the humans are the masters and the aliens, the slaves. It’s a good, clear concept. Obviously it’s been concertinaed and compressed to fit 45 minutes, but it’s still a powerful central story.
As well as the role of the companion:
Donna wanders over to question an Ood. "Catherine Tate makes it very accessible," he continues. "She’s a celebrity and I think that the new series has tapped into this — the world of young people, where celebrity-hood is now taken for granted. Pop Idol, I’d Do Anything — Doctor Who is a part of that landscape of light entertainment now.
"It doesn’t seem at all odd that Catherine Tate should have a role. She somehow belongs there. It all seems to blend in."
