How Power Corrupts: Cognition and Democracy in Organisations Book

I think the principles in this book are just what I need and am grateful that the book was an easy read and will be easy to remember. I think the model is going to be quite helpful to me. Introduced to the principles by a respected friend and ally (and required by my boss to follow up by reading the book). But had I picked it up on my own, might not have bought it due to some style/culture issues. Anyone else find these funny?
1. How much of the book is spent telling the reader (or the characters who stand in for the reader) how extremely wonderful the ideas are. A total sales job, cover to cover. Even if what they're selling you is the life you always wanted, is that necessary?
2. How, since the teaching comes entirely in the form of a story, all the characters are perfectly lined up in their script, behavior, emotions... down to asking exactly the questions, using exactly the language in exactly the same way that goes with the system. It was a little eerie, that's all.
