Fishman Island is great, getting to see the straw hats interact again, the beautiful scenery, great flashback, very mature and understated inclusion of realistic issues with the tacking of race and inherited hatred, and some great new world teases at the end with Joyboy & Big Mom.
nothing villains besides hody who I feel works pretty well as the antagonist, and the princes could’ve just been 1 character, but still a very solid arc that doesn’t deserve the hate just for following muh marineford
