Now that the dust has settled post-Xmas and everyone's yakking about Sherlock, we can take that all-important bit of critical distance and talk at length about Doctor Who. Seriously, one of these days when we talk about brevity being a necessity, we're going to mean it. Not this month, though. 

Rob and Clive are joined by film-maker and nu Who-hater Keith Eyles for a spin through the past and present of Doctor Who with, as befits a show with time travel at its core, the future. 

Warning: contains gratuitous use of a sonic screwdriver.
