It's a delightful film: I must highlight the creativity of the unique and entertaining animations, along with the excellent soundtrack, ideal for watching with the family. The friendship that develops between the protagonists, Kai and Lu, is captivating, with great chemistry, full of funny moments and catchy musical rhythms that keep you glued to the screen from beginning to end. I especially love the aura of magic and mystery that surrounds the story, which explores the tales of mermaids and their musical abilities. Furthermore, the film reflects on how fear and misunderstanding of the unknown can lead people to make the wrong decisions. The only downside is that the story is a bit slow, but everything else was great.
