One Piece viewership was down for season 2, and now the 12-season plan doesn't seem all that likely

The team behind Netflix's One Piece may have a 12-season plan for the anime adaptation – but now that it's been confirmed season 2 pulled in less viewers than season 1, it's seeming less and less likely it'll ever come to fruition.

According to Forbes, the show's second chapter earned 16.8 million views in its first four days of streaming: 1.7 million down from its predecessor during the same window. In the grand scheme of things, sure, that's not a huge drop. But waning interest from built-in fans isn't a good sign when it comes to longevity potential, especially when it bagged a 100% Rotten Tomatoes score and you consider that each episode reportedly sets the streamer back $18 million.

"There's so much material," producer Marty Adelstein explained to Deadline earlier this week, in reference to the original manga's 1,080 chapters. He went on to say that they could plot out six seasons "easy", but that's the least they imagine when it comes to the adventure drama's future.
