A quick google search shows that OP contains very little pure filler episodes (relative to the length of the story), the issue is the pacing and the filler moments to stretch out the canon content. One pace is a pretty good way to avoid those moments, or reading the manga which you can find in color. There’s a lot of nonsense in this comment section lol
The point of the journey being the most important part is correct, but I take issue with the description of that being filler. The term filler would imply those parts of the story to be worthless and without effect on the progression of the story at large. Every arc of One Piece (barring the actual anime only filler) has value whether it be development of characters or laying groundwork for future events.
That being said some canon episodes includes filler for the pure reason of it being an anime adaptation. Sometimes it just doesnt flow as well. I wouldnt quit one piece bc of that propaganda lol. People also j tweaked out because oda loosely said the story is really starting now. So people j be doing the most and try to hate on it when they can.
I actually really enjoyed Skypeia. I was on the brink of stopping when I hit skypeia and Enel (eneru) was such a fun villain so I pushed through more and I enjoyed Thriller Bark as well. Shockingly, I couldn’t stand the water 8/Ernie’s lobby arcs. It was awful. I also quit one piece just cause I tried so long to like the show, but I just couldn’t take the pacing. The most I think I’d do is read the manga once the author finishes it
