I'm so disappointed, can't even express it correctly right now.
This entire chapter was fools gold galore. Nice on the outside, but totally without substance, if you look at it again more deeply.
It was literally only about the standoff in the end.
We didn't learn what Luffy said to Ace/Sabo back then.
We didn't even learn what the prophecy about the "young generation 20 years in the future" was about exactly. Just some vague hints again.
That was not a worthy chapter for that kind of milestone. Sorry, if I hurt some fans feelings, but that's the hard truth.
