I enjoy series like this for the sheer diversity of documents used in the research. I find it inspirational from that point of view.
However, I think the breadth of social history was lacking a little in the latest series. The previous properties featured had seen more changes in their internal layout and usage as well as in their surrounding neighbourhoods, reflecting all manner of political, economic and social changes. This series had comments about the general growth of Leeds and the fortunes of the textile industry, freemasons and theosophy but these didn't seem to impact greatly on the house itself - though the lives lived by the inhabitants were interesting and varied.
