The 2007 anime is a quick watch, sitting at only 5 episodes. While you may initially be led in by the smoke-like hair of the main character Afro and a gritty introductory scene, the show falls very flat afterwards.
You will immediately recognize the heavy blaxploitation inspiration throughout and while that is perfectly fine, any show in my opinion needs a fairly well-written story to fall back on as the appeal of visual aesthetics can only get you so far.
Compounding the lack of a good story, it is very difficult to get invested in any character and their arcs (even Afro to an extent) as the writing is below average, at best. A majority of the dialogue hinges on dated African-American cultural archetypes, with it almost feeling like a purposefully awful dub of a 2000s anime. Even the ending is lackluster in most regards. It overstays its welcome which in turn hurts its narrative impact.
Luckily, the show doesn't overstate its welcome too long with it's 2:30 runtime over the whole series. If you sit down and view it as a fun, yet hollow thrill ride of a anime, then you'll have a great time; just don't expect much nuance or substance beyond the surface.
