Only Wano is extremely bad other than some hype moments and few fanservice moments. Rest of the arcs doesn't have notable inconsistencies and flow was good despite pacing issues. For example, Dressrosa up to Doflamingo putting up bounties was excellent. Then Luffy running towards doflamingo took so much time just like 990-1000 chapters. And G4 time limit for 4 chapters. Other than pacing, dressrosa is fucking awesome. Same for WCI, first half is top notch up to BigMom wedding cake. Only saving grace for second half is Luffy vs Katakuri fight. Reverie is short but peak one piece. PH and Wano are the shit arcs post TS compared to other arcs, with PH at the least. So while Wano is a disappointment, rest of the timeskip arcs are semi good to good.
