To be honest, that's similar to my motivation for finishing it. I think this is the first book I decided not to stop reading just for the sole purpose of writing a lengthy rebuttal review.
I actually will not say that his techniques are bad/wrong/poor. But it's really shitty to keep trashing Ivy league MBA programs and then advocating the techniques taught by those programs. To date I've read 3 books from The Harvard Negotiation Project and another from, I think, Duke. For each chapter in this book, I want to highlight his techniques and then specify exactly where the same advice appears in the books he criticizes.
I think it actually would have been a great book if he wrote with more integrity. His book is easy to read and practice. If his techniques work, then he has a legitimate advantage over the other books, which are much more complex. It's a pity he made a potentially great book into a lousy one.
