I absolutely love this story...love it to pieces. Gareth Roberts really did something great with this...a historical figure with a twist.
The episode had a real feel-good factor to it, was nice and quaint and didn't involve a massive 'end of the world' kind of story either. It was probably the last episode of the brilliant fourth series before events took a darker turn - a turn that would see us all the way through to the Moffat era.
I love the Ten and Donna relationship too. Utter friends through and through, and the sort of story that makes her eventual fate all the more tragic, as you see what it is they lost here.
Brilliantly written, acted, directed, produced and the sunny shots of the house are beautiful. I know this is an episode that divides opinion, but I just thought it was wonderful and quaint.
