The Zatoichi TV Series

Following an eleven-year, 25-entry run of feature films, Shintaro Katsu would continue to portray the blind swordsman for over a hundred additional television episodes (before returning for one final movie years later). The show basically follows the same formula we'd later see with Bill Bixby in The Incredible Hulk: a vagabond wanders into town, gets entangled in some local conflict, and is eventually forced to unleash his deadly alter ego before walking away to somber music. I'm a total sucker for it.
