David Higgins says it all for us, a terrific series for lovers of France but completely spoilt by the recaps and to-ing and fro-ing between the various locations.
A much better idea would be for each episode to concentrate on one Chateau and follow the story through with no recapping after the adverts. Most people have a memory span longer than the adverts.
I have complained to c4 about this but of course no one has bothered to reply.
