This is one of those sequels that returns exactly to the scene of the first movie, like Back to the Future II (time travel) or Return of the Jedi (Death Star). Here Zatoichi returns to the place he was sort of forced to honor-kill the dying samurai in the first movie, but a buncha people are super pissed at him! Unlike the first movie, Zatoichi quickly and frequently fights large gangs of assassins because we don't have to wonder if it's a myth that he's so great (because why would they make 26 fucking movies about him being a good liar). It's not as good as the original but it's still fun to watch Zatoichi act like a loveable clumsy doofus until he's forced to kill approximately 100 people with his cane sword.
I just recently finished watching all twenty-whatever James Bond movies and wanted a new series to watch, so why not the Zatoichi samurai movies I asked myself, and I said ok, sure, just watch 'em. In this first film of the 26 film saga, Zatoichi, a blind masseuse, shows up to a gambling house. It turns out Zatoichi is basically the Japanese Daredevil (though, hm, it beat Daredevil's creation by a year so I suppose Daredevil is the American Zatoichi) - he may be blind, but he has enhanced other senses and swordsmanship to take over. Anyway, he's one of those swordspeople who realizes killing is bad, m'kay, so he doesn't want to get involved in a big gambling house war, even after he meets a dying samurai named Hirate who befriends him and begs him to fight him. I'll let you guess whether or not these two swordsmasters fight by the end of the film!
