What a terrible "review". Maybe you should retake 5th grade English first. HxH is not a manga aimed at 12 year olds. There is death, complexity, logical fight systems, genocide, etc. It skirts the edge between Shonen and Seinen while making itself palatable to those looking for the former. In a sea of shonen series with protaganists winning fights by sheer willpower, bad guys changing sides because they were "forgiven" once by the good guys, and incredibly predictable story arcs, HxH is a breath of fresh, Cynical air.
