I am currently watching One Piece on a regular base and i must say i was pleasently suprised about this special. You could compare the special to an extended filler episode, they meet new people, encounter a new enemy, etc...

Like said before the story is equivalent to a filler episode, if you didn't like watching the One Piece fillers, then don't even bother to watch this. However there where some nice aspects to the storyline that kept me going.

Typpical One Piece anime style.

Once againt he typical music of the One Piece episodes. Nice pirate music, what do you need more?

Story: Even though this is just a special the whole aspect of the story is pretty exciting. Although the main enemy is pretty lame, the journey is what makes it worth while.

Animation: This special didn\'t get made until a couple of years after One Piece aired so when this tv special was made the quality of OP is very good.

Sound: Great One Piece music. Need I say more.

Character: The main crew is all there and they are done all as good as they get.

Enjoyment: Very enjoyable, everything I have said explains this all ready.

Overall: If you love one piece and havent seen it read more

Story: I give it a 6 on story. I really enjoyed where it was going, how everything flowed, however it was still missing something for me. Still a good story though. I think it would have been better had the special been a bit longer, or if this was turned into a feature film with maybe an extra half hour.

Art: Good. I'm very pleased with it.

Sound: Great! Everything is clear and easy to understand.

Character: Best aspect of the whole movie! The story focuses on a bit of story for the side characters, but it involves read more

This is by far the most enjoyable, entertaining and well-writen of all the specials and ova’s. I frequent it above all others since it will immidiately lift your spirits everytime your feeling down.

The story, characters and the setting of the plot, all fit extremely well with the big upcomming adventure mood that the first two season have. You can really tell that the makers of this ova, did their uttermost best to emulate the entire scope and feel of the story and the characters.

Most of the movies can’t hold a candle to it. If one should make a list of all the movies, specials, ova’s, read more
