The Fourth Great Shinobi World War is the most Disappointed arc.
I was disappointed that Kishi couldn't spend more time on building up the rookies with not enough screening time and some Character Development, and instead, Kishi decided to Kill off my Favorite character, Neji Hyuuga, who never done much through out the whole shippuden where he should deserve more actions of a worthy oppoenent but instead fighting off Fodders.
I'm also disappointed with the edo tensia since the fight was too short or skipped that Kishi Couldn't deliver. The edo tensie didn't bring any sense of dangers because it only killed off fodders with no importance of the characters whatsoever. Kishi made very fast pacing wars which it could've had alot of good potential.
Luckliy, Studio Pierrot decided to add fillers based on the wars which Im hyped up, because its adding more screen time on the characters, more actions, expand the plots, more in-depth, etc which Ive wanted to see. I dont care what anyone would say, but I consider these fillers as canon, and I want the studio Pierrot to make FIllers for the war with all the time and efforts all for the sake to make to make the BEST SHINOBI WORLD WAR ARC in history.
The Fourth shinobi war is probably the worst arc in manga, but probably the best arc in Anime.
