I saw this movie shortly after it was released on DVD, such a great film that came straight out of Japan.
The movie is about a young mermaid/fish girl named Brunhilde by her strict father. She later sees the surface and runs away from home to see the rest of the world.
A young boy named Sosuke finds her after getting trapped, and names her Ponyo. He first thinks she's merely a fish, but later finds out that she can transform into a human-like girl.
I really liked their friendship, and all the hardship they have to endure through the course of the film.
Ponyo is a creative spin off the Little Mermaid legend, and features wonderful animation in addition to a great story. Fun for the whole family.
