Redundant and unnecessary.

Admirable film.

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

This movie is by no means an excellent film. This film is a throw back to 80's action flicks with an emphasis on martial arts and the Ninja subculture. The acting is not very good but the action set pieces are excellent! This movie showcases Scott Adkins amazing martial art skills and stunt work. Anyone who grew up watching 80's action movies and ninja movies will enjoy this film. The sequel to Ninja is on par with this movie and I'm always surprised that Scott Adkins hasn't been tapped to do more mainstream movies. Overall I found this movie enjoyable and I hope they continue making sequels as long as Scott Adkins is the main hero/character.

The plot is pretty weak in this movie, and lacks a really intense story, despite trying so hard to be intense. It gets by on some incredible fights with Scott Adkins, and quite frankly, I bet I'm not alone when it comes to people watching this movie, simply because of Adkins. It starts off a little slowly in the first half. Tsuyoshi Ihara provides some great intensity, and some good villainy, but it lacked the proper excitement for me. Once the second half begins, things really begin to heat up. The action is so strong, you tend to block out the average story. If Adkins's subway fight sequence isn't enough for you, then Adkins's going completely ballistic in the finale, by making many martial artists look foolish will definitely hit the spot. This guy is incredible, and if given the chance, he could be the action star the genre has lacked since the heyday of the 80's action heroes. I wouldn't call it a great performance, but he acquits himself decently. If you're not blown away by some of Adkins's moves, I really question your judgment. His love story with Mika Hijii isn't anything groundbreaking, but it's moving enough. Speaking of Mika Hijii, she's far from a damsel in distress. Not only does this woman kick major ass, but she takes a beating like a champ. I cringed in some of those scenes, but she held her own big time. It's pretty violent, if you like that sort of thing. I personally like violence. The finale is a bit over the top with the dramatics, but it does the jobFinal Thoughts: See it for some of the terrific action scenes. Scott Adkins won't let you down. As long as you keep in mind that it's not a great movie, you should be able to find mild enjoyment. I didn't mind it. I'm actually curious about the upcoming sequel5.3/10

I agree with some review that this film does take the concept of the old America ninja film's & makes it better for todays martial art film's & with Scott Adkins playing the lead role make's the martial arts fight scene so much better.What this film does as well, is capture the true beauty of Japanese martial arts & the way of a samurai fighting with the sword. It also capture the culture of tradition, discipline & training of Japanese martial arts which really set a realistic tone for the film.I find this film brilliant done those who say that Scott Adkins can't act seriously haven't got a clue in acting because you give any actor the right role, that where the acting skills shine through with the right storyline & character.This is a brilliant made film, the fight scene are amazing with Ariel combat kicks special the one scene with Scott Adkins really show homage to the great Bruce lee with taking on a lot of guy on at once just one hell of a brilliant fight scene.This is one film I recommend you watch if you loved the 80s America ninja or grow up on martial arts of that theme this one wont disappoint.

This is better than any other US made ninja movie I've seen so far. The depiction of the Japanese culture is very authentic, although no such school of ninja really exists, the scenery, the outfit all are what students of kobudo (ancient martial arts) actually wears in their dojos.The quality the producer and the director put into this movie shows. Casting is good, and we see A list Japanese actor Tsuyoshi Ihara playing the antagonist in this movie. The movie starts off in Japan, and ends in the US. Transition is believable, and right actors are placed at the right places. This is not like the "Fast and Furious Tokyo Drift" where the actors are all Asian Americans, and shot in LA. Everything fits in, and writer and the director shows their understanding of this genre.Outstandingly well made movie, this is one movie that's worth watching.
