I think there is some middle ground between 'Slavishly copy' and 'is written by someone who read about Doctor Who once in the Radio times'. I'm torn on it, there are a couple of neat ideas in there but as part of the celebration I would have liked to have seen a story that was actually about the Doctor as he was not as he could be remade. Otherwise what's the point of having a 50 year celebration?
I guess the real question is who this is actually intended for? Doctor Who fans or Colfer fans?
