We had about a 50/50 like vs. dislike on this one at our club. Many thought the book's title didn't explain the author's view. They felt like the author was very negative about all types of people and was a black and white thinker. I had several "aha" moments in this book when recognizing people who were already in my life in his descriptions. Interesting sort of 'self help' book for people who want to improve relationships in their life.
