No problem broseiden. I particularly recommend The two animes GiTS and Kit. GiTS pretty much sets the standard for cyberpunk anime. Kite was my intro to ultraviolence. Its about a little girl assassin that shoots her victims with exploding bullets. Things get very rapey and very gory.
Also a note about 'Shogun Assassin.' Its the first two 'Lone Wolf and Cub' movies edited together to make one movie. They guy that made it had lip readers help with the english version so that the flaps line up perfectly. This leads to some very strange wordings, and awkward line reads. "I AM THE SUPREEEEEME ninJAH!." comes to mind. The narration of the little boy is done by a very young little Sandra Bernhard. Yes, THAT Sandra Bernhard. Shogun Assassin is fun, but If you want the real deal, download the actual 'Lone Wolf and Cub' movies. IIRC there are six in all.
I have not seen Sanjuro, though I have a copy of it. I have seen the movie its a sequel to, Yojimbo. Yojimbo is one of Kurosawa's most famous movies, and the inspiration for 'A Fistful Of Dollars,' which is the first in the man with no name trilogy. (The last being the already mention 'The good the bad and the ugly.') As some one who is very much a movie snob, Yojimbo is one of the greatest movies ever. Then again, you can say that about all of Kurosawa's movies. Sanjuro is supposed to be more of a comedy. Despite having never seen it I know its great because Kurosawa made it.
You should just download all of Kurosawa's movies. You can usually find them in one big torrent. They were just about all released in high quality as part of the Criterion collection.
Anyway. I dunno if you can tell, but I'm kind of a film snob (and an animation snob.)
