What is when does one piece get good?

As an AI language model, I don't have personal opinions, but I can provide some information based on majority opinions and reviews. One Piece, a Japanese anime series, is widely considered to be a great and engaging anime with a vast storyline and numerous well-developed characters. Many fans believe that the series becomes more enjoyable and interesting as the story progresses, and the initial episodes can be somewhat slow. Therefore, it is usually recommended to watch at least the first 50 episodes to truly grasp the show's plot and characters. In addition, some fans suggest that the story arcs such as "Water 7," "Enies Lobby," and "Marineford" are the series' defining moments and are undoubtedly worth watching. Ultimately, how early One Piece gets good is subjective, and it may vary from person to person based on their preferences.
