The theme of the show in a word is "Revenge" you combine that with a Ronin element and basically you have the ingredients for a time-tested winning formula. The story never gets complicated (doesn't need to) or boring (with all the blood n guts how could it?) and that is because of the crisp animation style and fast-paced action sequences.
The voice acting is also top notch, with Samuel L Jackson doing a good job as the brooding Afro and a spectacular job as his eccentric conscience. The villains in the show really make watching it worthwhile because while the hero is straight out of every western revenge flick ever made, the villains are original and their characteristics are entertaining.
All in all, it's a fun ride for the 5 episodes.
