The way we (English) have treated Germans since 1945 is utterly embarrassing. Macmillan's generation had an excuse, even Thatcher's to an extent, but since 2006 things have only got worse. I love working class Brits but going on about the Wars and 1966 all the time is boring and offensive. Probably will remain the same for the forseeable future, not sure whether Brexit will have a positive or negative impact here.
I think the best word for this is 'dry'. Expecting to dive right into the realities of late Victorian relations (that whole "since 1890" bit of the subtitle), the reader is instead treated to a history lesson that goes back to the Middle Ages. The World Wars felt glossed over, and then way too much time was spent discussing movies.
