Rurouni Kenshin has a t.v. series isn't that bad in the violence factor save a couple Scenes (the suicide of Udo Jin'e, fight between Kenshin and Saitou, etc) and thiers some blood.
However, I prefer to watch Samurai X: Trust and Betryal. I just love the animation style and story line. It does get extremely violent. But I think it makes the watcher realize what indeed happened at that time and the realization of killing.
As for Reflections, I like it (just watched it again today
). I don't like the fact that it doesn't really follow the time line of Rurouni Kenshin nesscarily. Though I found it very sad and touching.
