What it is, is something that has been known since chapter 1: it's the greatest treasure of the greatest pirate that ever lived, which is more than enough motivation for pirates around the world, including the protagonists.fexus wrote: When your series is named One Piece and have gone this long without even a hint on what that One Piece is, even calling it decent writing is a bit too much.
What it exactly consists of is a mystery, and usually the presence of long lasting mysteries within a story are signs of well thought writing, not the other way around, like you seem to be implying.
One Piece can get somewhat bulky and some arcs can be too long, but that only means that some arcs could be more trimmed, not that the writing for the characters and plot isn't good.
Your conclusion of "long lasting mysteries" plus "long series" equals "less than decent writing" seems to be a pretty faulty conclusion to me. Following that logic, "A Song of Ice of Fire", the series of books that the TV Show "Game of Thrones" is based on, has less than decent writing, since it's a pretty long series which has long lasting mysteries ever since it started in 1996.
