"One Piece: The Movie" was released in 2000 as the first feature-length film adaptation of the popular "One Piece" anime series. Upon its release, it received mixed reviews; fans appreciated seeing their favorite characters like Usopp (voiced by Kappei Yamaguchi) and Young Woonan (voiced by Takeshi Kusao) on the big screen, but critics noted that its plot and animation were somewhat limited compared to the evolving standards of the series. Over time, the movie's reputation has evolved—while it may appear dated by today's animation technology and storytelling complexity, it holds a nostalgic charm for long-time fans. It is now considered a cult classic among "One Piece" enthusiasts, appreciated for its role in expanding the franchise and offering a unique adventure involving pirate legend Woonan and the quest for his lost treasure.
