This movie is based.
This is a Japanese movie about the bushido samurai code. 12 rogue Samurai and a bandit take on 200 samurai of a tyrant lead samurai. The movie is pretty much a live action anime. If you like anime, you will like this movie. I'm not a big anime fan, so I thought it was kind of boring at parts. There's no moral preaching or hidden propaganda. It's just about samurai following bushido code. There's a 45 minute fight scene at the end. I just enjoyed it because there was no woke BS. I think the story is ficticious, but I don't know how historically accurate it is. The movie is in Japanese with English subtitles.
