Query: Boring, not much substance, stereotypes galore

I could not finish reading this book. Boring, without much substance, full of gross stereotypes and generalizations, this is at best an article. Somehow authors managed to stretch it into a book. Way too long, fails to engage the reader. They run courses on this topic, if they talk about the same stuff in the same way, I can imagine what that must be like ... I'd prefer a root canal job, thank you! Pass.
