How is Wano worse than WCI? You probably love Big Mom's wedding cakeee screams. Strawhats having a walk in the park in a Yonko territory with their weakest members is somehow considered good writing these days.
WCI was far from perfect but :
- The Yonko threat was far more present in WCI. Wano except Kaido was way more of a joke
- Kata vs Snakeman is one of the best fight and had one of the best choreography in the manga
- BMP >> BP, way more creative original, better powers, more threatening, better organisation, personalities etc etc. Enraged army was cool. Totland island was great,
- Everything up to the wedding explosion was kinda great or good
- At least for once the story wasn’t linear and wasn’t the typical OP story
- At least for once post skip the story of one of the SH had dev instead of just being old gags and jokes again and again. We can think whatever we want about Sanji dev this arc at least it was something. Far far faarrr better than the whole nothing we have for the other SH
- Pedro was Chad
- Germa vs BMP was kinda cool
and I likely forget some things
Wano was a disappointment from the beginning to its end. The big arc to end the main arc of post skip and the Yonko saga fell flat so bad. The fights, the story, the characters, the stakes etc etc. Some stand outs but a weak arc.
