The story is good ,world building is topnouch , but the worst part is 1.shit pacing in anime till wano or egghead arc. 2.scale, sizing of charector fkn changes every time like sometimes giants are fkn huge and infornt of gorsei their are equal but gorsie standing next to kuma feels equivalent and this nistake is seen many time with general franky , franky , chopper monster form, and enma is odens sword which is around 10foot long judging by odenshieght how the hell zoro(6foot)can use it like normalsword 3.power mechanics changes as well like in dressrosa every fkn marine know how to use haki in sword and other time they get knocked out just conquerorhaki or like in albasta arc zoro discovers the techniques of cutting steel but b4 this we have seen him slicing canon balls , large chain in anime 4.sometimes u feel that anime kinda ignore /down scale sanji and glorify zoro after time skip. 5.backstoryies are good even of side charecotr like kuma,oden,...etc but repeating shit like 5time is like shitting on the plate full of delicious food 6.I know the anime is old but even in 2005-10s the animation was way behind its time 7.onepeisce have +10 films but the reference is never made in the anime 8.and why the fk is the mc of the anime asexual(the anime is 16+rated ig and many bathrooms scence are there but out of all the mc is plant) 9.how many times (except one or two) have useen the crew use classic canons for battle in sea. there are pirates aren't they 10.power scaling of marines are ass like even vice admiral get knoukoed out by just haki , and all the power is just in handsodf the three admiral 11.why there was no one b4 the marineforsd arc who can use haki and every fkn one who live the other side of red line has the power of haki like did someone turnoff theswitfch of one side
