First off, I would like to acknoledge the fact this is a non-canon movie althought we will get back to this. It's non canonness doesn't change the fact that, althought being a movie that doesn't inscribe in any timeline, it's still pretty incoherent. The movie is a huge purge to watch and I have seen a lot of people online stating that this is an incredible movie, they should use those words more carefully. This movie has a lot of objective flaws that are not my opinion that are simply made here to attract the fans.
At out the way, I would like to talk about the good part of this movie. Some of the songs are great. UTA's singer does a pretty good job. She sings pretty well and some of the songs are a BOP. BUT, most of the songs are those kind of "disney princess" song where the caracter just talk about her fellings and it's really cliche.
Now that i talked about what I liked, let's talk about what's not to like in this movie. And for a movie starring Shanks, It was clear that there would be some fan service, but damn. This is my main issues with the movie. It has numerous, to say the least, fan service that are for most, caracters doing cameos. We have caracters taking part in the film that are neither pertinent nor justified. The movie has plenty of caracters that are like this. It is clearly made just to attract the fan boys and nothing else. You can seriously wipe out half the cast and the movie doesn't change. It's like the infinity war of one piece but not in a good way. You also have elements that are still not in the anime nor the manga that appair in the movie. It's just here to spoil the anime and this not good at all.
Also, another thing you can add that's pretty funny. One Piece's (the anime) biggest flaw is it's pacing. And right here the pacing is horrible. Everything happen really fast and you have things just coming out of everywhere. For the first hour, you just altenate beetween UTA singing and the lore of the island being explained to you. So you have all of these caracters that are completely disconected with the events that come here and just explain the lore and then she starts singing again. And another one comes and then she sings again. The ending happens also so fast you don't see it coming, not in a good way of course.
Furthermore, the guys who wrote this should be ashamed. (it might be like my review) They should of reread the things they wrote because most of it is so bad, even a 5 year old kid would of done something better. It was really really bad. You have a bid deus ex machina. Characters that had no intoduction that just pop out of nowhere to save the situation. There is also a plot twist that completely ruins the movie by the end.
The animation was also a big question for me. Sequences are action are just the caracters throwing their main signature attacks and that's all there is for the combat. No choregraphy, no movement except maybe for one scene. There is tho two characters who got some fire animation : Jimbei and Brook. But why them ???
And when you thought I was done talking about the flaws. There was a promess of Shanks being developed. And I'm sorry but Shanks is more developed in the trailer than in the actual movie. The only character in the movie that get's a tiny bit of developement is UTA and it's pretty bad. She transforms from a cliche girl that sings and is just nice, to a danganronpa character. She starts doing some wacky face and some weird poses it's random. Her developement is just really cliche. The writers clearly took no risk it was really a shame.
And I could go on and on with this movie. The 2/10 is more than justified. If I was a One Piece fan, I would be embarrased. "New Gen" Toei animation is really lazy and cares more about the money they can found in your pocket that in the work they can put out. I suggest you don't watch this movie, especially if you are not up to date on the latest scan because it does spoil some things for you. You can always watch this movie later. But even so, the writing is straight up bad and lazy and really the only thing you will find out of this movie is just a warmed up fan service from the One Piece "saga"
