Well, the T.V series was about average. But what caught my eay was the OVA series Rurouni Kenshin: Tsuiokuhen, I would give it a 9/10 it was awsome. The second installlment or ending to Tsuiokuhen was absolutely terrible. I kid you not it was horrible, almost as bad as Tekken!

So I reccomend the OVA (Tsuiokuhen), its better then the series also.

In the case of the series id give it 8 or 8.5/10
Hope I was of help.
