differin 0.1 Classic Doctor Who often featured quite a bit of running up and down tunnels, but in this story they couldn’t really avoid it. Designer David Myerscough-Jones pulls off a remarkable feat on Doctor Who’s limited budget in creating hugely realistic tunnels and stations and gives a sense that a wide section of the Underground is being brought into play. The sheer incongruity of seeing monsters in a familiar Earth setting make for a highly memorable story, and in many aspects a signpost for the way the programme would go in the Seventies.
