historical accuracy is for geeks
<sarcasm> First of all I'm a japanese historian so I did penalise you for inaccuracy </sarcasm>
The character designs and animation could have used some more work but were bette then stick figures and although the voice acting wasn't that hot you get points just for trying as most people do not. The fight scenes were pretty well thought out and the wakasashi move was very nicely done. And of course bonus points for ninjas.
