Finally, something original! Young boy learns his warrior father was killed by his evil grandfather, and the grandfather is coming after him next. What makes this so refreshing, is the eye-popping stop-motion/CGI animation, the Japanese action/horror combination in a kids movie, and a finale that is not determined by the blade of a sword, but by the "two strings" mentioned in the title. Best of all, Hollywood has made an effort to stylize Japanese culture through an American movie. If they could only reach out even more to this vast wealth of story-worthy material out there.
