10 Ways Russell T Davies Will Save Doctor Who

10. Familiar Faces

It's now old news that David Tennant and Catherine Tate will be returning to Doctor Who, with Tennant already having appeared in the final episode of Jodie Whittaker's run - as the Fourteenth Doctor. The task that Davies has is to prove why this rather obvious attempt to evoke nostalgia and win viewers back is anything other than simply that.

Did the Doctor choose this face for a specific reason, as was the case with the Twelfth Doctor reusing Peter Capaldi's attack eyebrows? The Doctor has reused faces a few times now, with Sixth Doctor Colin Baker having a supporting role in the show before taking on the title role.

The Day of the Doctor also introduced the idea of the Doctor revisiting "the old favourites", as it was heavily suggested that the Curator - played with glee by Tom Baker - was a future incarnation of the Doctor. Bringing familiar faces back is hardly a new idea in Doctor Who, and we encourage it, as long as it's given more than simply a fan service reason.

Still, even if this does end up feeling like cheap fan service, there's no doubt that Tennant's return will bring many people back to Doctor Who - specifically, those who may have lost interest over the last few years.
