Can i go back to Mizo's Loyal 47 Ronin; yes it's very long + testing if you want even some, never mind a lot, of sword fights and action (which i suppose is the general expectation of samurai films). But if you want an exploration of space then it becomes extraordinary. Darrell Davis cites it as the ultimate example of "monumental" Japanese cinema, and its style is certainly a sort of glorification of Japan's (historical) culture and philosophy. But as wpqx says that doesn't necessarily make for the most effective call to arms, even if it does address codes of honour + avenging a slight. Mizo had other fish to fry than simple militaristic propaganda. Instead of showing the main revenge action itself, he foregrounds the reaction of women (not for the first time). Far from his most accessible film but very rewarding if you want to take your time and engage with a completely different and probably unique cinematic experience.
