Query: Goju Ryu 03:Essence of Karate

Higaonna greatly underachieves with this tape which has the potential to be a valuable addition to the martial artists video library. It is, however, sadly incomplete. The impression is little effort went into this production which simply shows the master punching and kicking at his student, who theatrically flails around. There is no explanation of any of the keypoints of execution of the techniques. I would say the tape is "interesting" but the customer absolutely is not getting value for the money. Not recommended.
