imo everything that came out after dressrosa was very bad, mainly the yonko saga, zoo arc and the reverie were all right.
oda awakened a tendency to turn the major players into complete clowns:
-the marines after dressrosa climax, their contribution was insignificant like always, fujitora ruined the marine portrayal by bowing to king rico and broadcasting it to the public, instead of taking action against doflamingo.
-the revolutionaries after dressrosa, lost their headquarters to blackbeard pirates, lost the battle during the reverie, and their biggest L is seeking refuge in okama land.
-big mom in her own arc and beyond, no comment.
-kaido is just a very powerful clown with a badass design, no leadership, no planing, big mom invaded his territory without consequences and manipulated him into an alliance.
-the world government during onigashima, their recent display of incompetence is very concerning for the end of the series.
