"Very interesting, with a lot of good insights"
I have read all the complaints, and all I can say is that, yes, sometimes it did get a bit boring. But never for long. And, in retrospect, the boring parts were difficult but necessary to explain the point the author was making. All points were valid, and everything was backed up by studies. Even when the author was just giving an anecdote, he would then back it up with a study to show relevance.
I highly recommend this book.
