Really very good, focuses on the political and social side more than Napoleon, though he still does feature heavily. I will certainly be getting more books from The Great Courses.
I developed an interest in United States Presidents having watched the excellent drama-doc "John Adams" a few years ago, so I was a bit disappointed that my he only got a C in Mr Davis' somewhat erratic scoring system, but on the whole I found this narrative very informative.
Details did somewhat jar: pronouncing Andrew Jackson a racist who earned his fame by his genocidal attacks on native-Americans and then giving him an A (or was it an A+) seems a tad random, and to go through the entire gamut of 20th Century Presidents without even a mention of that eminence grise for many of them, J.Edgar Hoover also seems a little odd.
However, I do know more about all American Presidents than I did. The presentation was good (although the repetitive if informative lists did not lend itself to an audio-book format).
I can definitely recommend to the novice student of the topic.
