The animation holds up well. It's smooth. It does a good job capturing how the manga looked in the first 30 or so chapters. Everyone is so expressive and the battle scenes were so well animated! I'll admit, I was getting a tad bored of it near the end, but it wasn't bad. It was entertaining, especially at the end when the little girl had that life preserver on Luffy. This was made before the anime and it wasn't even Toei who made it; everyone sounds different obviously but it's not too bad and the music in this is amazing, it honestly reminds me ofa 90s video game!
