First of all, I wanna thank rickylrico (http://myanimelist.net/profile/rickylrico) for reviewing episode of Luffy. If it wasn't for him, I wouldn't have created this review or watched the episode/movie in the first place.
So let's begin!
Story: It's great.. It's like a movie because it runs for about 1 hour and 45 minutes. It begins when Usopp announces the "Strawhat Crew Fashion Show", it's basically just an intro, then they get blown to an Hand Shaped Island by a huge cannon ball. The Strawhat Crew help an old man get a special doll back to his son that is currently in the Navy and they stop an ugly, evil man/woman/other/not specified from destroying the island with a huge cannon.
Art: A bit of the new style, it's like One Piece Movie 10: Strong World's art if you've seen the movie. If you haven't, then you'll be surprised.
Sound: Same soundtrack and amazing as usual.
Character: Everyone is funny and the same as always. I'm pretty sure you get the gist of it if you've watched One Piece before.
Enjoyment: You WILL definitely enjoy this movie/episode, considering you're into One Piece.
Overall: It's really really good! 10/10!!!
The credits are nostalgic af-! You'll see why.
