In order to lure noted fantasy author Neil Gaiman back to write another episode of DOCTOR WHO after his Hugo-winning story of last season, “The Doctor’s Wife,” show-runner Steven Moffat asked Gaiman if he would like to make the Cybermen scary again.
Neil did; and then he did. Make the Cybermen scary again, I mean. And he did it, rather simply and realistically, by following a “natural” trend in technology: getting faster, better and smaller. The Cybermen have gained the ability to adapt on the fly; they can move faster than the human eye can follow; and the once-fearsome Cybermats have been shrunken down to tiny Cybermites. And worse, the Cybermites can be thrown at you! And then they crawl all over you and attach themselves to your face. Yuck!
