Query: Lost track along the way

When I first started reading this book I thought I would stand the fact that is was too long. It was well informed, interesting and at times entertaining. My feeling was that I would rate it with at least 4 stars. Somewhere along the way I think Johnson lost track of his argument. He started covering too much material with no structure and stating very personal points of view as facts. When I got to the Great Depression I decided to quit. I realized there were more better informed books out there and that I was wasting my time. It was unfortunate, the book promised much more than it delivered.
