Since 1963, entire generations have grown up with Doctor Who, and have been thrilled - and terrified - by the Doctor's adventures against some of the greatest evils in the galaxy, including the Daleks, the Cybermen and the Doctor's arch-nemesis, the Master. The show has been brought back to TV twice since its cancellation in 1989 (the first time, in 1996, being something of a non-starter; the second time in 2005 proving more durable) and has seen a complex and intertwining expanded universe of novels, audio plays, comics and even a set of Alternate Continuity movies. So someone obviously did something right.
