Ken is basically Bruce Lee on steroids living in a Mad Max post apocalyptic world. I personally love the series and while fantasy martial arts is the main focus the action is rather tame, I mean this is still an 80's anime series so don't expect explosive action but more intense buildup and graphic deaths even if the blood is censored to bright white for most scenes. The series has a strong story and really strong (in every sense) characters, it is dragged out at 140+ episodes but the series doesn't outstay it's welcome though some may feel challenged by the length and general pace.
