I have seen a few ninja films. Some were o.k., and others were downright awful. The legend of the ninja in most films was not portrayed very well. It would seem most directors wanted a lot of action in the film and played on the audience's ignorance. This film seems to do a little better than that. I have read a little on the history and techniques of the ninja, and even though this movie is dramatized, it seems to do well by the ninja. It makes the art of ninjistu, not only entertaining, but lets you see the awesome skill of its practitioners.
