1) The Strawhats are annoying except Luffy, Zoro and Jinbei
2) The Shichibukai were more carismatic antagonists than the Yonko
3) Celestial Dragons are clearly End of Series enemies headed by IMU
4) Marines Low diffied the pirates at Marineford
1)I find nami's and chopper's characters extremely annoying. The others are ok i think.
2) True. Kaido and big mom are more militaristic and imperial. They are more like mafia bosses than actual pirates. Shanks and blackbeard though, i find them quite carismatic.
The shichibukai had great diversity, character wise.
3) Probably yes but we ll have to wait to find out. I think that Akainu, blackbeard and im, all three will be the final villains, in the great war.
4) That is sadly true. I mean aside from top tiers(whitebeard and his commanders) and luffy, no one else seemed to have done anything impactful in the war. Oda's writing was poor in that matter. Some high ranking marines should have died.
