Big disappointment here.
Art, sound, character design and animation are very good but the anime is ruined by
- a character who shows no feelings at all (except those of "his friend" who frankly after the first episodes start becoming more annoying than interesting),
- very anticlimatic narration and flow of events, basically... "Hey that's the bad dude and now he is dead"
- very mediocre story not expanded in any sensible way.
Watch I'll summarize Afro Samurai plot in one sentence:
The bad guy killed my father, now I'm gonna grow up and make my way of blood througt out a mass of weak, insignificant extras to beat him in 4 episodes. Oh yea, some friend of my childhood is there somewhere, as if I care.
Waste of time, even if you're in just for fights, there are far better alternatives. The only thing for which Afro Samurai is good is to take a cool screenshot as screensaver, but you have already Google. So save your time.
