After reading basically all of the comments here, I'm gonna dissent and say that the first 300eps of one piece are great and I disagree with people saying they aren't. The show is not a speedrun. I loved the openings and endings. Skip the recap when it grates on you because over time it gets longer and longer; I remember some episodes having like 6 minutes of recap, which is absolutely unacceptable, regardless of how complex the war-like battles with multiple factions are.

I was greatly saddened by the decision to get rid of outros, and the double length into drags. The show can admittedly be slow in a lot of places, but nowhere near as egregious as a lot of people make it out to be. I LIKE shows that take it easy and have world building and vibe building.

If One Pace does it for you, though, all the power to you. That's a great project.
