You kidding lol?
-Having so many wasted panels on dull ex-villains like Lucci and Kaku already gives this arc -3 points from the start.
-Filler panels with Luffy "struggling" with kid cyborgs.
-Overall, fake tension when a top tier like Luffy is around, at least in the other arcs Luffy didn't reach this tier so we could have reasons to justify his carelessness.
-Luffy and Zoro teaming up with Lucci and Kaku, blergh.
-DF's origin is an asspull, they literally grow out of nowhere because of dreams... (maybe we still have chance for other explanation since that wasn't the true Vegapunk).
-Shanks wank (again) and the resolution of the conflict with Kid pirates.
-We discovered that Akainu is an incompetent. WG decided months ago to wipe out Eggisland and he didn't even notice that 100 navy ships and Kizaru went there until they sailed lol. No, did he actually know that it's 100 ships or only that Kizaru went there? lol
Still, there's hope if we will have an actual fight with the Navy.
