I watched it because I'm a big fan of Frank Skinner and he's been desperate to appear in Dr Who, as anything, for years.
I was pleasantly surprised with how much I liked him as the Cheeky technician character,Perkins. Will he become a recurrent character I wonder.
There would be a slight issue of how similar he and Capaldi look..although maybe there's some mileage in that, "Here Perkins put my clothes on and speak to the Alien Blob thing".
It's still for kids though (although what time did it go out? I taped it but I'm sure it was pretty late for what was always a Saturday, 6pm, show).
