Meh, better than the previous post-timeskip arcs but that doesn't take much because most of the arcs post-timeskip aren't that good, Punk Hazard, Fishman Island, Dressrosa were band average arc so it wasn't hard to top them.
But yeah I agree WCI is a massive disappointment ; Luffy vs Katakuri is hands down the worst fights in One Piece history, we got 10+-chapters of Luffy running and trying to figure out ultra instinct, and then Luffy wins the fight because Katakuri decides to handicap himself.
Let's not talk about the "Year of Sanji"... This is the biggest meme about the whole arc. Sanji has been so useless this arc it's hilarious, months of build up with Sanji cooking a cake... for what? Literally nothing.
It's sad but the only reason I'm still reading One Piece is because of Wano, only Zoro greatness can save this manga.
