The main strong point of this movie is its style, common to the anime series, so when you watch it you're almost ready to believe that this is one more canon adventure of the Straw Hat crew (unfortunately, that feature is not usual for One Piece movies). And the main message of this movie - that money and gold are not the right things to value - is seen here as clearly as in the early episodes of One Piece (Orange Town arc, for example). If you expect the movie to be like a continue of the original story - you won't be disappointed
