Visually stunning from start to finish. They made sure that even if most people don't like this film, the animation will make everyone captivated. The plot is just a post-apocalyptic Little Mermaid from the opposite perspective which they remind us again and again in an attempt to make sure no one, I mean absolutely no one misses the reasoning behind their choices. Even with such attention to detail in animation and sound effects, the film manages to be bland a lot. Despite its blandness, they did manage to make the animation itself work in the narrative a lot to make it worthwhile too. It's really a mixed bag where if you like the animation you may like it.

This film is gorgeous. Absolutely gorgeous. It has some of the best animation and music I have ever witnessed. The physics-defying scenery, parkour races and flashbacks create a very colourful and dynamic atmosphere.

However, it barely had any story. The characters are just stand-ins for typical anime tropes, the romance is forced and there seems to be no overall "point". The entire plot could be described in two sentences without any loss of detail.

The graphics, visuals and "choreography" are interesting and fun to watch and keep your attention all the way through, but in the end the story is a letdown. No rhyme, reason, or point to this movie. The characters are semi-interesting but not deeply developed.

This is just basic action / adventure anime with a pseudo-romantic story thrown in. It seems the writers / directors were trying to say something, but it never really comes across as being very important. Basically it's just a fairy tale without a lesson to be learned.

I give it 6 stars for being interesting to watch, but it came very close to receiving a "mediocre 5". But had to give it an extra point for good graphics.
