Query: Badly dated material, pretentious, hard to follow

This book appears to have been created many years ago and now looks its age. The techniques are disorganized and the book includes many pages of questionable and hard to figure out "options." The author was showing off and we readers must wade through page after page of needlessly difficult massage instructions. The art seems dated too and is poorly done. Much of the book is devoted to "Shiatsu" a Japanese therapy that can be very painful and doesn't belong in a massage book. To summarize: a little useful material here and there but many techniques employing "pressure points" and similar quackery. Really not worth your time.
