Sasuke should have never found out the truth about itachi, it was better for the story, but not for his character,konoah would have found him and he would have just went back to the leaf
the edo-tensei zombies, were also not that good, imo, at first i thought it was gonna be great, but they were very weak, the only fight i liked from the edo-tensei was itach & nagato vs naruto & killer bee
kishi never shows anybodys full power, it seems like madara's power has been reduced ever since he became jinchhuriki, for some odd reason,then he got another power up (The holy tree) and we still didn't get to see his full jinchuuriki power, same thing with obito, he had good powers, but they were never displayed properly, even naruto & sasuke, sasuke got a justu from hashirama (Never used), and he got hashirama's cells from kabuto and hashirama's chakra and naruto already had most of the tailed beasts chakra in him from the fist bump, and he got even more when obito gave it to him
Obito becoming the sage of the six paths, was also a mistake imo, he seemed strong enough to handle the alliance in his regular form, with the help of madara, and even when became so6p, he still got his ass kicked
Everbody wanking the shit out of nowhere in the war, "this is naruto's feeling" "omg naruto was so lonely back then", like we didint know that already
mostly every akatsuki's death, except for Nagato's,konan & itachi's, those were legit but the way everyone else died, was "meh"
Konoah 11 barely getting any shine, until the very end of naruto, very dissapointed on how shippuden forgot about so many characters
