This manga is my favorite manga in manga history and that's because, sure, the plot/action/ninja shit is good (not always), but also and most definitely because of Sasuke and Naruto's relationship. It should have been a shonen'ai. IS a shonen'ai. A terrible well written one. The ending is pretty disgusting, but if you ignore chapter 699/700 this is the most wonderful love story ever told (also with the best unresolved plot EVER) - the two main characters are worth it.
Really, I'm not usually into spokon manga, because, let's real, it's not the same as watching the whole thing animated, you know? So yeah, I personally like spokon anime, but getting me to read the manga is a real accomplishment. Haikyuu!! managed it. I love the manga almost as much as the anime. It's just super exciting and the art is too cute. The protagonist does an awesome job at being addicting.
How do you review One Piece? There are so many things to say and not enough space. One Piece is genius. It's an exciting story in a skillfully portrayed fantasy world. The author is crazily awesome at dropping hints of things that will happen 300 chapters later, demonstrating to be following a real plot line and never leaving anything unexplained. It's terribly long but perfection. You can't get enough of it.
