1. Could give it 5, but I think the first one and the third one are distinctly better. I thought he could have included more on the process of passing the Civil Rights Act of 1964 and the impact it had on his relationship with his former allies like Russell. His habit of referring back to quotes in the earlier volumes is getting a little annoying, as most Caro readers love these books and will remember those earlier passages quite easily, but there are other audiences out there, which brings me too...
2. I've been ridiculed for reading these books, and not by traditional idiots, but by achiever-class types. It always takes the form of "What a harmless but bizarre eccentricity to bear." It really is disturbing that people who, for better or for worse, we rely upon to handle many of the important tasks that move society forward (or backwards, or into a brick wall) are so wrapped up in the here and now that they literally ridicule a meticulously researched study into how the most powerful country in the world was shaped over the course of the 20th century.
