think the background is so strange.
In the war against the gorvonment, Katsumoto leads only his family clan force. This is the battle style of 16century in Japan. But, this movie is taken place in the end of 19century.
In this era(Bakumatsu and maiji ishin), the young people in bushi class seem more frexible. They obayed their "Hanshu"(the leader of each county) and "Hangaku"(the ideological tendency), but they can make their own bloc party. The model of Katsumoto is oviously
Saigo Takamori, and the big part of peole who fought with him is young people who sympathized him.
So in this age, the ideology is more improtant than family tradition for young men to make their dicision.
"The Last Samurai" doesn't describe this aspect at all. It feels strange to me.
But, the other items and key words roughly belong to this age. So, this is confuses me more... But the armors are strange. Maybe they use them but...
they belong to more 16century than 19century.
And add to that, in non-Japanese movies, they always grasp Japanese sword in wrong way.(Exept "The Last Samurai") When one use Japanese sword, one must keep left hand on the very hilt on the sword. Right hand is on the upper part. To do so, one can use more one's strangth when one swing the sword.
Too long writing...
At last, my favorite character is Katsumoto! He is cool. I think his lifestyle is respectable.
