It seemed to me too lighthearted, reinforcing all the preconceptions and prejudices a lot of people have against Germany. The big mistake was the silly idea of taking what is 'average', and then relentlessly trying to comply with that. The idea that the woman had to carry on for two more hours doing housework in the flat which did not need it, was an daft example.
Coupled with Rick Stein's food programme of the previous evening, I doubt either will encourage people to flock there, which would be a great pity.
PS. Nurenberg contains the national art collection and is the birthplace of Durer.
