For me, Doctor Who has always been at its best when mixing the new and vibrant with older, nostalgic things. However, I'm not really a fan of the show so I don't think my opinion counts for much. However, when I have caught shows of the series just gone, I've enjoyed the inclusion of old character that have lit the lives of many generations of Doctor Who. However, the future of the show will be full of brand spanking new baddies for you to hate, according to Steven Moffat (who is about to become the show's executive producer and lead writer).

Moffat, who is replacing executive producer Russell T Davies, was speaking at arts and comic book convention Comic-Con in California, and told fans; "We're not in the business of being nostalgic, we're making nostalgia for the future, new monsters, new friends." Naturally, this was in response to some seriously nerdy questions like 'Ahem, will we see a return of Sarah Jane Smith, as played by Elisabeth Sladen in the 1970s?'

Moffat continued; "Doctor Who is at its best when it's brand new and you've always got to remember that there's a new bunch of eight-year-olds watching every year and it has to be original - it has to belong to them."

He continued some more: "Having taken the precaution of having memorised every single event in Doctor Who's history, it's fairly easy for me to keep continuity because I remember it all. In the end, a television series which embraces both the ideas of parallel universe and the concept of changing time can't have a continuity error - it can't. It's impossible for Doctor Who to get it wrong because we can just say 'he changed time, it's a time warp, it happens'."

Moffat is known for writing some of the best episodes of Doctor Who, including that frightening one with the weeping angels. Asked about this, he said: "If people are worried that because I'm taking over Doctor Who it's going to be just really, really frightening, if that's your concern then... tough."

Dark side Doctor Who coming soon...
