If Russell T. Davies had instilled this sort of educational and morality in the new series of Doctor Who, we would have something more akin to the Original series, which, even though I was only young when it was being aired and I never managed to catch either Troughton or Hartnell, was a fantastic series.
Sarah Jane Adventures has humour, monsters and story lines that, although they are hidden behind children running around and on a children's network, are just as accessible to adults than to children.
The characterisations are clear, the directing good, the effects up to scratch with those in Doctor Who and the acting, dare I say it, better. They tackle emotional issues, far-fetched plots and links to the Doctor Who series old and new and still come up Aces whilst being slightly educational along the way.
Whether it was intentional or accidental, adopting the whole point to the original series (Being educational and for the family) The Sarah Jane Adventures should hopefully continue for a long time and be given a n equal focus to that of Doctor Who and far beyond that of Torchwood.
Keep it up Cast and Crew of a fantastic series.
