Not everything he said is true but he was right about Sanji baking a cake and he's of often right when it comes to this kind of things so who knows
It's a deduction from his own analysis which I respect, but you should take it as speculation from an analysis expert nothing more. Which can be right or wrong at the end of day.
Poetic ending would have had:
- Law or Rebecca ending Mingo
- Nami ending Arlong
- vivi having hands in Crocodile's demise
- Wiper finishing Enel
and many others.
Sure, it's poetic to have Momo do something with Kaido, but to ignore even the likes of Law or Wiper who were VERY strong and had the means to hurt both of Doffy and Enel during their arcs, and now Oda decides to give it to a child!???? Momo? nevertheless against a Yonko???
If that's not bad, then I don't know what it is. Poetic is nice when the person is capable of delivering, yet Oda ignored poetic with Law and Wiper who had every means to pull a win, now he'll do it with a powerless 8 years old kid????
I mean, kill me if that happens
