The best thing with this series is its stupendous attention to detail and historiocity. I have never seen anything that is as authentic when it comes to gear and weapons.
The show is also lewd, constantly showing near nudity and alluring to sex. Not my cup of tea but others might like it.
The story is philosophical. Is there any point to stop violence, strife and bloodshed? If Hollywood made this it would have been simplistic good vs evil. But the Japanese are more sophisticated philosophically than the Americans. So even thought the show is a bit silly as a whole, it does not shy from the truth.
My main gripe with the show is how medieval French nobility and class structure is portrayed, especially considering the hundred years war. It is unfair to the French nobility. The typical course of the war was that the Normans that ruled England created expensive and competent professional army. Went over to press their claims in France. And to force the French to do battle they looted, raped, murdered, burned the french countryside until the king and the nobles were shamed into offer battle. In practice, they nobles were much appreciated by local peasents when they came to combat the english. The main complaint of the peasants were if the king did not come and protect them. This is turned on its head in this show in some simplistic class struggle theme.
Anyway, I watch it for the authenticity of houses, arms and armor. It is truly created by some mighty Japanese autist, most gratifying. Its also why I give it a high mark. There simply is nothing like it out there.
