A lot of people would find this movie probably just a big mess of throwing characters in from every arc and so not a lot of actual dialogue went on between returning characters with the straw hats. But I feel the purpose of this movie, since this is the 20th anniversary movie of one piece, was trying to fit all the characters in and bring back some memories from the pass and how far they've come. So as a long time fan, this movie was the perfect amount of excitement. I am bias so would give it 10/10, but just the movie itself I would give a 7/10, so my rating Is closer to 9/10.
The art was really all over the place, I can tell they were really trying for that 3d animation there, and included all these different art styles. A scene when the main villain takes his "form" , that scene was just straight out of like a King Kong movie and didn't match the rest of the one piece movie art at all, but it kinda worked for me? Like he looked pretty epic in that scene and it made me feel like, damn that is Stampede right there. The fact that the art and animation was just all sorts of styles kinda made me feel like, "Yup, that's One Piece for ya."
Overall it was still good old One Piece. It had great comedy bits, and although not fully emotional scenes, they were somewhat present. This movie I felt really covered most of the One Piece journeys feelings pretty well. So nvm the story, it was just a fun get-together festival.
