Fishman Island: 8 -- It was a great arc to start OP after the time-skip.. It had a lot of narrative concepts and had a great historical background that served a lot of importance for the present arc as a whole.. The characters we were introduced to, like King Neptune, Caimie, Shyarly, Otohime, Shirahoshi, were likable and had a lot of unique character and role in the arc.. We also had jinbe coming back to the story.
We also had something that ties to the void century - joyboy's letter - and poseidon, as well as stuff that foreshadowed what the future will bring as well. The only thing that ruined it was Hody being Arlong 2.0 and the obvious villains...
But I do like Hody's motives: "nothing" .. which ties a lot to the story behind Otohime and even Fisher Tiger as well. And it was a refreshing change tbh, to have the SH easily overpower the villains for once, and display how much stronger and reliable they've been after the time-skip.
Punk Hazard: 4 -- Not much to say really... except that 90% of this whole arc involved running, running, running, running, running... and I still didn't understand what was the whole point of Law heart-switching the straw hats... and for a set-up arc that involved running 90% of the time, 60 chapters is a bit... ehh.
Dressrosa: 7 -- I liked its unique story, culture, and the background behind King Riku and the shit he faced because of Doffy... Doffy and Law's backgrounds were great as well. Luffy vs Doflamingo ain't bad at all, and narratively speaking, Dressrosa as an arc was great. The only thing that marred it was the pacing and the fact that things just dragged on for too long, especially in the colosseum. Fuck the birdcage too..
Zou: 10 -- Not gonna lie.. it's the best thing post-time skip.. everything was handled differently compared to how arcs in OP run as usual, like the way Jack was defeated (not by the usual SH crew, which was starting to get incredibly trite by then), the info overload even for a short arc etc.. it was incredibly refreshing, and I liked the characters we got introduced to, the history of Zou, its unique culture etc.
WCI: 2 -- Jesus Christ!
Reverie: 6 -- Things got really interesting, and a lot of stuff got revealed here: Im, Ryokugyu, Sabo and the rev executives, Kuma, Bonney's background, Rox etc, and we saw characters we've known before, like Vivi, Cobra, Wapol, Dalton, Kureha, Rebecca, Viola, Shirahoshi, Neptune, Coby, Garp, Hina etc... but things just ended abruptly.. I mean, wtf... I was looking forward to the reverie, and then *poof* it fucked off.
Wano: 9 -- the only things that ruined it a little for me was Luffy's mini-training arc in Udon as well as some of the lame underlings of Kaido we've had, like Hippo-guy (who was so irrelevant that I have no idea what the flying fuck his name is), Babushka and Holdem.. Even Urashima was more interesting as a character than some of these lame ass villains. But aside that, I've been loving Wano so far.
