On the one hand, this was quite dry and I did find it a drag in places. On the other hand, would you really want this subject matter to be anything but factual? It was well researched and well argued, and ultimately enhanced my understanding of a difficult subject.
As this was a collection of essays it didn't need to flow, but there was a mixture of factual content and analysis of different interpretations of the primary evidence. Browning was quite persuasive, though in all honesty I know so little of the minutiae that I would probably take everything he said as read. The last essay in particular was very illuminating, and in a way reassuring given the number of people who couldn't carry out the horrific orders, and who were essentially army reservists.
