Absolute staple of cyberpunk influence. One of the best drawn mangas of all time. Great premise with great characters. Unfortunately it collapses on itself the further it goes on. More and more uninteresting characters get introduced and the story moves away from its central themes: what it means to be human, the connections between body, soul, and emotion, societal hierarchies, finding purpose in life, and just becomes a somewhat run-of-the-mill sci-fi story.
Still, I recommend it to the point of considering it a compulsory read for all fans of manga.
