I read this book with some colleagues at a work book club, and I think it's interesting how split the opinion on the book is among readers.

My impression is that there's some good ideas in the book, but it suffers from not being thorough enough on a theoretical level. Many definitions given are NOT consistently used, the book frequently falls back on discussing things in a very OOP centric way, and a lot of stuff came across to me as just opinion pieces.

Some stuff I found was excellent, like the notion of module depth.

When reading reviews on Goodreads, there's a similar disparity between people who really liked it and people who are critical of it.
