As the first "One Piece Film" it clocks in at 51 minutes. It is a glorified 3 part episode, and has the early series entertaining charm. The small cast (before the series expanded greatly) really helps the pacing of this, letting the narrative work around the Straw Hat crew. While there's no real stakes and the villain is a one-note joke, the film is fine. Not great, not bad, but just fine.
