Although I have not seen this video in it's entirety, I have seen excerpts of Mr. Wilson's "kendo". It's obvious for any knowledgeable person that he has had little or no formal training in kendo. This is my opinion based on 25 years of practicing kendo.If you must have training videos, e-bogu sells some that are made by Taro Ariga, a well-known international competitor. But really I'd recommend you find a dojo if kendo interests you.
