I agree it's too much detail and it might be a little straining, but I think it's worthy the effort. There're cool things about it and new informations that are really interesting. What I like about it is that it works with the psychological from each character and shows their line of thought, as well as really exploring the source of power (Nen), which completely lacks in series like Dragon Ball, imo. It's something you can see is well thought and the fights, as well as the characters' chanches of winning seems way more realistic than in One Piece, wherein it's put a lot of emphasis on just will power being what will lead you to victory, although not in all instances.
