I recently began watching all of One Piece. No skipping filler, watching every movie, every OVA and ONA, etc, and out of all the movies and smaller stories I've watched this one was my favorite up to this point. The supporting cast got along with the Straw Hats neautifully, and the concept was interesting enough. The setting is really cool, honestly I wouldn't've even minded if it had been a little longer. The animation and soundtrack are what you'd expect from One Piece at the time that this aired, nothing particularly different. Like I mentioned, some really good scenes with the Straw Hats are whatmake this movie so special, there's particularly a really great Sanji scene that I loved, I really hope he gets more wholesome moments like that in the future, there's so much potential to him as a character and I really love him a lot! Overall a really enjoyable movie, definitely watch if you enjoy One Piece, even if you usually skip the non-canon stuff!
