If tptacek hadn't destroyed it in such detail, his review would have consisted of saying "Hey, this book is pretty bad; it's got some very serious issues, and makes some pretty terrible or misleading recommendations. My suggestion: do not read it".
Would that be better? Or would you be complaining that "Well geeze, it's not helpful to say that the book isn't good; you have to go into some detail about what the problems are so that everybody can learn!"
The idea of asking for LESS DETAIL in a criticism of a topic is bizarre. How much detail would you prefer?
