I havew read that review and I didn't find anything wrong with it. That person clearly acknowledge the book for what it is. He even discusses things with you. So I find your critique a bit out of place. He gave an honoust review that was only 3 stars.
I also read the other 3 star review. It also got some bad comments from other people. Why is that? I haven't seen the book yet nor read it. If I have the cash I will buy it. But now it seems you can only give honoust reviews if they are 4 stars or higher. That doesn't sound right to me.
