If you liked "Ninja Assassin" then you may wanna see this, especially in the "blood and gore" department. This is another "classic" Manga/Anime that blew up the scene back in the days like "Fist of the North Star", "Guyver" and stuff like that and it's still a cool as flick to watch for me.
The story is cool and I'm always down with the whole "Ninja" thing. Awesome drawings, kick-butt voicing and blood is constantly splattered generously. Although it's quite old it's still better than some the "animated flicks" made these days, even better than some "live action" ones too, but then again that's my opinion.
It's been a while since I'd seen this and watching this again was still a great experience, I am glad I found it online because someone burrowed my DVD of this and I haven't seen it since. I might buy another one. Maybe.
