Lone Wolf and Cub: Sword of Vengeance (1972)

I often complain about a lot of comic book movies being all origin story and exhibition with a bad guy in there somewhere that doesn't really figure into the action too much. If he does, it's not until the end and it's brief. Then there is the big bad guy, hovering about, but there is never a real fight with him; instead we have to go off on another story after every time he shows up to spout some exposition but not contribute anything more than that. The reason I bring this up is, although they are called manga to distinguish the stories from American comic books, manga are still comic books. While Lone Wolf and Cub: Sword of Vengeance is not about a superhero the story still follows the same basic line, and it is based on a character created for a manga series. The series is a classic in the chanbara (or swordfighting) genre of Japanese movies, and from what I understand the sequels largely excel in telling better stories, but this first entry is severely hampered
