THUNDERING NINJA is more cut and paste ninja nonsense in the Godfrey Ho mould; presumably he and his crew were hiding behind all the westernised names in the credits of the international release. As usual, a non-ninja related crime film from the 1970s is re-dubbed and newly-shot footage of random ninjas battling in the woods is inserted into the mix. The result is hopelessly confusing, and the presence of Jimmy Wang Yu - one of the most famous kung fu stars out there - in the original re-dubbed film is a constant distraction. As for the new ninja scenes, they're very goofy, but not enough to make the film enjoyable.

Holy crap, this is the greatest thing ever. Ninjas, titties and bad overdubbing. This movie is so amazing. I'm watching it right now. Ninja action scenes are A++. The ninjas are everywhere and they're awesome and ruthless and they're either spying on someone or killing them or being killed by a more skilled ninja. Every ninja in this movie is 23 times better then Jackie Chan in every way.Everyone needs to see this movie. EVERYONE. I got it cheap from some bargain bin. I can't believe someone would sell something this fantastic for two dollars. Man, even the white guys have bad overdubbing. There are regular ninjas, there's a red ninja and a white ninja and a big boss ninja at the head of an evil organization. Evil organizations are the greatest. Especially when they're run by ninjas that laugh manically way too often. This movie wins. Wins everything.

This movie is SO impressive, I have watched it two times today. With no plot line or appropriate ending, I have to say I have found the best lousy ninja movie ever made. To match the caliber of the movie, I will summarize it really badly. It's for some reason about ninjas and then there is an American agent for some reason that ends up being a red ninja for whatever reason, and apparently it's important to be a red ninja. Then he fights and they use stop frame to make the ninjas vanish really poorly. Then there are ninjas blowing up and then the red ninja does his kuji-in hand movements and explodes or something then the movie is over.I bought it for 5 cents at a thrift store. I would have payed two, maybe even three times that much for a movie this good.

This is the greatest movie ever made. See it. If you can't find it, go to Canada and buy it for 99 cents (Canadian). It will change your life forever. It's good because there is no plot, but there are ninjas jumping around trees and stuff. Jesus likes this movie, why don't you?
