Being a fan of Stephen Hayes, I was excited to see his name on this in what seemed to be a ninja vs the Ku Klux Klan. Minutes into the movie, my instinct told me it would be a loser when it opened up with an overweight topless woman changing. What does this have to do anything? I asked myself. Next followed a sorry excuse for a hero with no combative skill, athletic ability or common street sense whatsoever. What the heck was he doing in this supposed ninja training? A junior high kid track athlete would have put this "hero" to shame. Ninja Vengeance was a misleading title, since there was obviously no real ninja doing much of anything. It should have been called "Blundering Youth Stumbles Across Rednecks". The acting and dialogue was as cheesy as something a double digit IQ person would have inspired. You end up not really caring much about any of the characters in this film. Don't waste your time.
