A mad man once said that every fairytale needs a good old fashioned villain, and he was very wise indeed. Where would our favourite protagonists be without their malevolent, loony counterparts? Every consulting detective needs a consulting criminal and every idiot Time Lord needs a sophisticatedly idiotic Time Lord (but which Time Lord is which? Thats for you to decide!). Both of these renowned antagonists are masters at being masterminded criminals, masters of disguise and, well... the Master of evil. Moriarty may as well be a rumoured incarnation of the rogue Time Lord, somehow marauding London before regenerating into a Mary Poppins-esque killer nanny, bound to ruin your childhood of umbrella flying, levitating tea parties, dancing penguins and magical carousels. A complex, incommunicable relationship exists between these villains and their mortal enemies. Both Sherlock and the Doctor seem to admire their foes' persistence and commendably pernicious triumphs (however gruesome they may be), almost regretting to obliterate whatever domineering scheme is tossing, turning and boiling over in their insane and morally twisted minds. Can't Moriarty and his extensive web of criminal associates win for once? Heroes can be sooooo boring.
