The animation is good, but not too good. Not bad either, but a little grainy. The plot is complex, but not really thought through, and it is not conveyed in an edible manner. Things happen too fast, characters all look alike and you don't know where they came from and why people care when they die. The fighting scenes are decent, but I think they used too much of that "slow motion after the sword hits" which actually doesn't show anything, just the spurts of blood.

Watch it if you want to be sure you see all Japanese anime with ninjas :) but other than that, don't bother if you have something good to watch.
