The Tale of Zatoichi Continues
What they share
Both films are directed by Kazuo Mori, and they sit in Action / Drama territory. If that's the register that drew you to Satan's Sword III: The Final Chapter, the second film will land in a comparable space — through a different lens.
What The Tale of Zatoichi Continues is
You wander back to the village where a year ago you put down Hirate and sleepwalked out. Now another swordsman lingers, a face you once loved and fought.
