Mugen no jûnin: Immortal

I came to this because the manga was a big inspiration for the video game Sekiro. I thought the whole series was wonderful. There were a lot of characters, and I did get the feeling that some story lines would have made more sense if I'd read the manga. Which I might now do.

I loved the main characters and felt real concern for them. A lot of emotion was conveyed with very little dialogue and minimal animations. I found that very impressive. The violence was impeccable. And very graphic.

I imagine I will watch this again at some point.
