The difference between the classic Dr Who and the modern reboot is that the new Dr Who episodes are usually stand-alone stories, whereas the classic series were serial stories told over several episodes.
The classic series therefore were much scarier, utilizing the cliff-hanger at the end of every episode, and were quite terrifying and memorable for children as a consequence. The final image of a Dalek trapping the Doctor against a wall and screaming “EXTERMINATE!” would leave a child shuddering in terror as the closing titles began. It truly was the stuff of nightmares, and the stereotypical concept of a child watching Dr Who from behind a sofa was certainly based on a real shared experience.
The modern Doctor, on the other hand, is far more sentimental. The stories often centre around characters and the poignancy of time travel and grief and loss and missed and found opportunities for love and affection and saving people we care about, often through sacrifice.
I like both formats.
I never would have found myself crying at the old Dr Who, but stories like Father’s Day (2005) are very moving. In the newer series, the acting and appeal of the Doctor’s companions and their relationship with the Doctor are far more important. My favourite companion, for this reason, has to be Rose.
But I do miss the terror of the classic series and their pervasive atmosphere of dread. Doctor Who FTW!
