The problem of Oda this arc, everything feels unreal, it is up with stalling and some action here and there but that is it. You can feel characters like Luffy,Zoro,Sanji,Kizaru or the Gorosei, no one is going really all out. They just use minimal efforts, some new move there and that is it. Luffy barely has any scratch and that after fighting Kizaru,Saturn and all Gorosei...
Sanji also faced Kizaru and Nusjuro and totally looks fine.
The difference in wano and here:
In wano it was actually a serious situation, strawhats been at their limits, been badly injuried and show all new skills and go all out, similar how the villians gone all out.
Here in wano, characters barely show anything new. Kizaru acted like a Pacifista, no awakening, no CoC move, Gorosei(except Nusjuro) also doing only minimal effort.
Oda stall this arc by running and stalling, he don't want to show much of characters powers, characters look like npc characters, which leads again to no tension. None strawhats is even serious injuried.
That is Oda biggest problem in this arc.
I still hope it change somehow but I doubt it.
Ancient Robot going to show up soon and wreck around.
