Doctor bloody Who

A long time ago, when I was young, I watched and enjoyed Dr Who. It was, and still is, a sci-fi children's programme with lots of goodies and baddies, implausible plots, a stupid 'time machine the tardis,' and just a hint of sex.
50 years later it is still going strong and it is still a children's programme. Why do the BBC trail this bloody programme as if it's some great meaningful blockbuster. We have been reminded time after time that the next series starts on August 26th with the latest incarnation of 'The Doctor' and his sidekick. They will no doubt face the latest new evil characters as they travel through time and space and will of course exit victorious. I'm sure that children will enjoy it but surely it gets puffed out of all proportion?
