Agree that it depends on the actual complaints, but in general, I'd say that those arcs indeed didn't live up to their hype, and the complaints, even if exaggerated, still have a solid ground.
I dislike Wano more than WCI, I did re-read WCI some time after it ended in a chunk to compare it to the arcs I'd previously read not on a weekly basis, and it felt better. With Wano I simply don't want to re-read it, I'm just happy it's over, Oden's wank is over, and I really enjoy Egghead so far.
