Rurouni Kenshin is generally a great series that focuses on a few interesting themes, punctuated by cool fight scenes and strong relationships--both friendships and rivalries. Despite largely seeming to fall in the "historical fiction" genre, some of the lore is just categorically silly (e.g., Kenshin being able to move faster than the speed of light). But Kenshin is a deeply lovable character, simultaneously a half-witted klutz and an incredible warrior with unfaltering conviction. The worst thing about this series is that it was left unfinished. It apparently excludes the third and final story arc of the manga, instead following up on the excellent Kyoto arc with filler (although it's admittedly some of the best filler in the show... one episode involves an implied erotic dream). The full-length movies are supposed to be substitutes for this exclusion, but they're pretty bad and one of them is not even canon according to the series creator.
