Kaze no Yojimbo (Wind of Yojimbo)
This show is what "Samurai 7" is to "Seven Samurai", another modernization of a Kurosawa classic into a modern anime.
Largely overlooked, mostly because of its title in Japanese and its lack of giant robots, Kaze no Yojimbo is a perfect example of creative license taken with a show, and its brilliant execution.
Two rival gangs war constantly in a quiet, rural Japanese town. A mysterious stranger named George Kodama finds the town in search of a man by the name of Genzo Araki. Though his initial questioning of the locals proves to be fruitless, he perserves and sticks around the town for a little while.
After fighting off some local thugs, they realize that the mysterious stranger is an amazing martial artist. When the leaders of the gangs find out about this, they try desperately to enlist his aid to tip the scales in their favor.
The sleepy town has more to it than is initially obvious. What are the gangs fighting over? Who is Genzo Araki, and why does Kodama want to find him? Better yet, who is this Kodama guy anyway?
The characters are sympathetic. The show paints very few characters as being dynamically "good" or terribly "bad". Most of the characters, especially the gangsters themselves, are just people looking for opportunity: being in a corporately sponsored gang pays more than being a farmer anyway.
The sound quality is excellent, and there is quite a bit of attention paid to detail. The animation on the other hand leaves a bit to be desired, especially towards the end, but that is not altogether uncommon.
The voice acting is good both in English and Japanese, though I personally favor the English voice actors. The voice actor for George Kodama in the English dub tends to feel more like a man who quietly and confidently understands the workings of the world around him, whereas the Japanese voice actor tends to play more for the role of the samurai that Kodama's character was based off of originally.
