Samurai X is a series based on the beginning of Kenshin Himura. It is a beautiful, theatrical insight into Kenshin Himura's mind. It shows you how his beliefs were formed and his history. If you want to learn about Kenshin's past this is definitely the series that you want to watch. The animation is beautiful, fluid and cinematic. Although the voice actors are ok [Kenshin sounds like a goth girl with a deep voice] but for some reason it seems to fit. I like this series so much that I bought it all. Also if you like violent anime that also incorporates romance, you should check this series out.
