Oda is good at world building but shit at plot writing. The lore he writes for each arc are always good ( except Wano) and the islands and settings look great. But the plot is always the same....
Bad guy threatens island -> Princess/Damsel meets SHs and becomes friends -> Princess/Damsel needs help to defeat bad guy -> SHs defeat bad guy and have a party.
There has been a few switch ups those usually involve ticking time bombs and needing to escape the island such as Impel Down and WCI. But yh usually most arcs follow the same generic forumlas.
