Things are looking up for Dr Who after an abysmal last series.
David Tennant was excellent when he started, but his performance had definitely become a bit repetitive and self-referential by the end of the last series. I put a lot of that down to trying to get some screen time next to the wild gurning and random yelping of the talentless ball of ginger cat-sick they'd landed him with as a travelling companion.
There's only so long that many actors can take being defined by a single role (look at the way people who haven't played James Bond for 30 years are still 'ex-Bond', or all the soap starts who jump ship when they realise they, in the minds of the audience, are indistinguishable from their character) and he has taken the chance to leave.
Russell T Davies did a brilliant job of reinventing the series for the 21st Century, but he also seemed to have written as many variations on a theme as he could, and I'm pleased that he has taken the decision to move aside.
If they had gone for a bit of 'stunt' casting with David Morrissey or Eddie Izzard it really would have been time to put Dr Who out of its misery. So casting Matt Smith, someone with minimal previous exposure, shows that there is at least some serious intention in the BBC to continue to reinvent and develop the series, rather than just cynically milk the existing franchise until it runs dry.
So good luck Stephen Moffatt, and good luck Matt Smith - the show is a bit tarnished and tired at the moment, but it might well be repairable.
