You have to remember that Dr Who has to be acceptable to kids, that is why it is on at 7pm and not 9pm. Which is why it is never going to be the same level as some sci-fi series. It could do better though, but it is now done by Welsh BBC who have a much smaller budget than its big brother. It was the scripted part with the Queen that ruined the story, that part could have been much better, and the actress was so crap. For the audience it is aimed at though, it was OK. They did break the age old rule though that two doctors can not be in the same place at once.
