I thought it was pretty good. Certainly some good lines. A little bit crowbarred inbetween a couple of shots from the end of Last of the Time Lords but that's okay! 5th Doctor was rather grumpy - must be a result of instantly being a couple of stone heavier - I think that would make me a little grumpy, too!
Perhaps a little too much writing to Tennant the fanboy at the end there but, again, I can forgive that as Davison was my first Doctor, too (I remember something of Tom but it wasn't until Davison's time that I really became a fan).
Of course it was a year early. RTD - no multi Doctor stories. Yeah, right! I suppose RTD didn't write it and this was, as you say, a charidee special! Still, hasn't Moffatt taken over as Producer yet?
Don't miss the Doctor Who Confidential on the Children in Need section of the BBC site (
