Just one fight after another

Seems to me this movie is just an excuse to stage one fight after another, linked together with a very flimsy storyline. For me, the only redeeming feature is the very attractive female ninja, but we don't really see enough of her.
If you want to see a much better female sword fighting movie, then check out Azumi, and the follow up, Azumi 2. Both have much better fights and believable storylines.
