Okay, the first chapter is overly apologetic, but keep in mind Ray Franz well understood the suspicious and negative mindset of the very people (JWs) he was trying to reach. He would be anticipating the kinds of thoughts that would be going through their minds in the event that they picked up the book. He had a lot of reassuring to do - especially about his motives and intentions.
Most of the anti-JW literature up until that time (1982?) had been robustly and even dogmatically anti-JW. Take the vile book "30 years a Watchtower Slave", as an example. Talk about cracking a nut with a sledgehammer. I'm sure that just as many people went running back into the organization after reading that book as those who ran out of the organization! :) Or what about the well-researched but stuffy and judgemental book Apostles of Denial whose author's name eludes me? I remember reading that book and thinking, Where's the concern and heart for the average JW?
Ray Franz' book is possibly the first expose on the Watchtower that blends respect, compassion and calmly expressed reason. The chapter that I particularly like is the one on blood - especially given the lives that have been lost over this cranky doctrine.
