One Piece is often considered "good" starting around the Arlong Park Arc (episodes 31-44), where the story deepens emotionally and showcases character development. Some fans also highlight the Baratie/Loguetown arcs as early points where the series becomes engaging, while others consider later arcs like Alabasta, Enies Lobby, or even Water 7 the peak moments. Overall, One Piece gets good gradually, with the early episodes laying foundational world- building and character introduction, and the emotionally intense and action- packed arcs starting from around episode 30 marking when many viewers feel the series truly hits its stride.
