I have a kind of a soft spot for this book because my friend lent it to me. Also, I have not come across other Wing Chun books to make comparisons. Having Ip Man's son as a co-author is a strong selling point.
It is a good introduction for total Wing Chun beginners that goes hand in hand with practical training. Written in plain English, with plenty of pictures, it seems suitable for both adults and children. The latter may end up asking who a prostitute is though - thanks to an unforgettable Ip Man anecdote!
I had an impression that the book presents Bruce Lee as an avid Wing Chun practitioner, seemingly ignoring his Jeet Kune Do philosophy and his challenging attitude towards tradition. Having just finished Little Dragon's biography, I saw the chapter about Bruce as an ultimate gimmick to sell you on Wing Chun. Funnily enough, I slacked so much with writing this review that I managed to read two more books in the meantime, one of them focused on Bruce Lee's philosophy. After that, I changed my mind. Even if Bruce's martial art ended up being something quite different from Wing Chun, his philosophy was heavily influenced by Wing Chun principles.
The book is very well illustrated. Ip Chun presents the basic techniques and Siu Nim Tao as good as possible in static pictures. This book could have been better if the authors included some of the more advanced moves or the breakdown of the second form. But then they wouldn't have a reason to write and sell another book!
