Dismal.
Comes far too late in the story, has zero foreshadowing of any real substance in Sanji’s words and actions before then and the characters introduced with it are all terrible. These factors combine mean every emotional beat fails to land. Compare it to the previous Strawhats leave stories of Nami, Usopp and Robin and it’s hot garbage.
Oh, and my own big pet peeve- half the Strawhats don’t even have a role in it. Imagine EL except Nami, Sanji and Chopper haven‘t actually went there. Awful. And the in-series excuse was garbage. ”If we brought the full crew it would be a war!” The full crew was ten people. The team that went to WCI had eight in it.
Nor did the ones that went to Wano do anything worthwhile before Luffy got there. In fact, I can even make Wano work better with all the Strawhats arriving at once, and the same plot points happening.
1) Same thing happens at arrival, Zoro tries to jump in to get DF user Luffy, both get washed ashore.
2) Act One commences near enough the exact same, only difference is Zoro is there at the beginning as well instead of meeting up like two chapters in.
3) Act Two starts with Zoro having being arrested for carrying Shusui, Yasu and Gyukimaru go to see Shusui, Yasu sees Zoro’s breakout and decides to follow him while Gyukimaru steals Shusui in the process. Zoro and Yasu go after Gyukimaru. Can even add in better Killer foreshadowing here and have him watching Zoro’s execution as well.
