Everything causes a war on this forum so whatever
Overload of characters, wasting panel time on Wano fodders and characters no one gives a shit about, trying to force readers to feel bad for characters who randomly popped out of nowhere 2 arcs ago and no one gives a shit about. Wasting Oden's plotline. The dude was hyped since Zou and turned out to be a massive clown who got finished by trolling Orochi who himself is fodder.
Land of Samurai = No actual strong samurai. Nakama power kicking in. Zero and I will repeat it zero fucking tension during a fucking war.
Basically under the roof is a rolling circus. Rooftop fight. Two of the strongest characters in the verse. Hmm, let's repeat standard shonen cycle wait, tank, hmm time to fight maybe?
80+ chapter of fucking build up just to see floating Circus.
NO THANK YOU, ODA. The worst arc post timeskip by far.
