Doctor Who's greatest challenge begins:
The ‘Christmas Special’ of Doctor Who saw the murder of this popular science-fiction figure beloved of the English viewers- by none other than the script writer himself.
The Doctor had always been a most dignified gentleman with an absolutely pure relationship with his assistants- a fatherly figure whose compassion blended with his superior intelligence, wisdom and knowledge. Throughout his numerous regenerations with various personalities and appearances; he maintained an untarnished character that had no ulterior, base motivations. This innocence was his ultimate strength.
Throughout the tremendous series with Chris Eccleston, a greater danger than the Daleks could be felt gradually closing in on the Doctor, which became apparent when guest-writer Steve Moffat noted he had based his story on a ‘sexual rivalry between the Doctor and Captain Jack’.
A further blow to this powerful innocence came when, just before his regeneration, the Doctor was made to give Rose a kiss.
Finally, Russell Davies delivered the death blow in his Christmas special: During a soliloquy, David Tenant ponders whether the new Doctor is a ‘sexy person’- turning to flash a wink at Rose.
He may continue saving the world for some time- but without innocence, like a building robbed of its foundations, is doomed to fall.
