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 ...

Mixed Feelings
There is something about the OLD One Piece that feels so; HOME. So welcoming yet strange to the heart, it has a unique feel that is rarely replicated, even by the same series 20 years later, the risks are lower, but still life-threatening to the crew back then, the world feels so much smaller yet very promising to explorers like the Straw Hats. And the adventures, as small as they may be, are always inviting and friendly to the third party that is the audience.

The story at hand takes place somewhere between Logue town and the entrance to the Grand Line, possibly before the Warship ...
