Query: Why does everyone else give this book 5 stars??

The bulk of this book is taken by yet another description of the form - and, in my personal opinion, form is something that can only be taught in person - thus the value is dubious.The section on "push hands" and da-lu is also very mechanical.And as far as the remaining "non-pictorial" part of the book, a much better - and more comprehensive - option would be "Tai Chi Touchstones" by D. Wile.
