>Repetitive plot
This is actually funny cuz the final part of pre ts was very innovative, but all the arcs post ts have turned into either "Luffy and the crew go save some island that's under Shichibukai/Yonkou very bad reign" or "Luffy goes rescue a crewmember " again, there was no need for Dressrosa, whose main plot was just them infiltrating in the Island and destroying the SMILE factory to be about "I'LL SAVE EVERYONE", there was no need for the Big Mom arc which was about stealing the Red Poneglyph to be a dumber version of Enies Lobby with Sanji
>Forced drama
Related to repetitive plot, we always need an Island to save, so we always need to watch sobstory number 20192389 so we can feel bad for them
>Goofyness reaching new levels
You can say it's just Oda's style but it isn't, I don't remember any Part 1 villain and it's crew, other than Buggy, being as goofy as Queen, and don't remember any Part 1 villain with a worse design than WB's son
>Hack World Building
Lots of people believe the World Building is good because it has lots of factions but that's solely because Oda made a completely retarded world that worked to perfection with its plot, there are 4 island continents, divided by a gigantic vertical line continent and an horizontal line of sea called the Grand Line, the Grandline is surrounded by 2 Calm Belts filled with giant monsters, every major sea can enter the Grand Line through one Mountain which has 4 streams connecting it, inside the Grand Line there are many different Islands, every Island has it's own "thing", one is Egypt, the other is Spain, etc, etc
Basically, Oda couldn't think of a normal fantasy world to fit the pirate plot in so he just made this shit up
>Luffy
A very bad main character, he is dumb and goofy at all times except when the plot demands it's time for serious speech time then he turns into Sun Tzu.
>Not really sure how to group it, but dumb shit like Luffy getting multiple Fleets off the Colosseum
