Well! I'm a thoughtful guy, and I like all 3 mangas, so!The Reviews:
Naruto
: Started out great. It had good characters like Naruto, and a colorful cast. The fights are great, the emotions were great. In the first part the characters were equally balanced and had good developments, with them training and gaining powerups. Things went down after the timeskip, Kishi lost his touch for a while, and Naruto became a fucking crybaby, while Sasuke went mad killing all in Uchiha name. That was the low point of Naruto. BUT after the death of Itachi and Madara's introduction things are shaping up again. Kishi introduced new characters like Minato actually fighting, Bee, Raikage, Akatsuki roster, Naruto (after telling Sasuke they will both die) became cheerful again, and things are shaping up for better now, with Raikage and the others being really good characters, Bee included, and with the war coming up now, Naruto is on it's way to revival. Especially since Naruto and Sasuke are becoming better and better. The only problem is Sasuke getting WAY too much panel time, but the story is becoming better.
Pre-timeskip Score: 9/10.
Post Timeskip score: 7.5/10.
Post Itachi Death Score:8.5/10.
Total Score (Not an average, story, characters counted, everything):8.75/10.
ONE PIECE: Ok, much has been said about it, and for what it's worth, it's really really good. Oda has been consistent with his characters, and he has a fucking badass main character, who is interesting, dumb, charismatic, and insanely likeable at the same time. Luffy really is a brilliant main character. I can't find a thing wrong with the cast, all are colorful, with their own stories, and Oda really gives them the deserved character development, which is all interesting. And if it fell behind Naruto in fights, Oda solved that with the Whitebeard War. The Whitebeard War, has, to date, the best fighting scenes I have ever seen. And though it fell behind Naruto after the war, Oda pulls out a 2 YEAR timeskip which promises to be badass, with all training. Unlike Tite Kubo, Oda has great storylines, comedy, action. Its a great Manga. With the Whitebeard war and Timeskip, One Piece has skyrocketed to a better manga than Bleach or Naruto.
Score:8.5/10 (Pre Whitebeard War), 9.5/10 (Post Whitebeard War).
BLEACH: OK. The Tragic Child. Bleach was my favorite manga for a while. Then it went down. Down Down Deep Down after the Karakura town arc. Kubo lost his mind, he kills off ALL the main characters, some very flimsily (Yamamoto). Aizen got way overpowered with the Hogyoku (His look Sucks with it) AND Isshin is a bad character (NOW). Ichigo is a poor character with only one attack. Just read the parts when Aizen goes to SS. Kubo kills off Gin, Rangiku arrives with no reason at all, and Ichigo's training isnt even shown, and his look sucks too. Kubo draws badly, HE HAS NO BACKGROUNDS at all after the Karakura town arc. He focuses on stupid characters.
Score: (Pre Karakura) 8.5/10. (Post Karakura) 4/10. SOrry, but it got really really terrible.
