The movie draws its story from the famous series Rurouni Kenshin. The government is beefed by so many especially Shishio who is totally out to bring don the Meiji government. In order to stop him, Kenshin trains with his old master to learn his final technique.
Handsome choreography, but it's mostly been a demonstration of the modern movie business's absurd gigantism: seven hours of set-trashing for a story that needed two tops. They'll probably reboot it in a decade, too.
