The story concerns the struggle between a woman's self-preservation and ethics. What Mermaid Forest lacks visually is made up by its ability to convey a strong message. The fact that this film teaches is more apparent than most other animes I've seen. Whether you agree or not it shows how simple humans cannot escape their fate, the attempt to do so results in consequences for those around him or her. It's doubtful that watching Mermaid Forest will alter one's life forever but I appraise it for succeeding in what it tried to do. I'm only bothered by how Mana, the most obvious victim, cares very little about what happens to her. I find that unrealistic and somewhat annoying.
