Plot

Fujimoto, a former human magician, and scientist lives underwater with his daughter Brunilde and her numerous younger sisters. Brunilde gets lost while she and her brothers are out with their father in his submarine, and she ends up on the shore of a little fishing village stuck in a glass jar. A five-year-old kid named Sosuke rescues her from the jar. Sosuke hurts herself when using a stone to smash the jar; however, Brunilde's licking of the wound causes it to heal almost immediately. She is given the name Ponyo by Sosuke, who also swears to look out for her. Meanwhile, Ponyo is brought home by Fujimoto.
In a confrontation with Fujimoto, Ponyo reveals that Brunilde is no longer her name and states her wish to take the name "Ponyo" and to become human. She makes her getaway, goes back to Sosuke, and starts a fantastic adventure.

Why you should watch it?

Ponyo on the Cliff by the sea, written and directed by Hayao Miyazaki, is based on the short novel Iya Iya En by Japanese author Rieko Nakagawa and has a number of historical contributors on the soundtrack, including Joe Hisaishi. At the Japanese box office during the year of its release, it was the most profitable movie.

No technological assistance is used; instead, a formidable group of seventy artists create hundreds of hand-drawn plates ( more than 170,000 pencil drawings were used, favoring the traditional technique over the computerized one) that frame in pastel colors the imaginations of Miyazaki. Ponyo on the Cliff by the Sea, is an animated fairy tale that enchants and moves with its purity and that predilection for essentiality that best captures the complexity of suggestions and sentiments of a story caught between dream and reality.

Stunning illustrations, lovely backgrounds, expressive colors, and most all, jaw-dropping animations that bring everything on the screen to life provide us with a truly visual masterpiece. The beauty of an ocean that has never been so accurately portrayed, as well as the variety of creatures that call it home, capture the attention of the viewer from the very first minutes.
With its waves, the sea takes on a central role, depicting the tension between man and nature—a relationship tainted by pollution but one that must exist for a life to be genuinely healthy. As per usual, Miyazaki finds the environmental issue to be particularly significant. He continues to explore it without ever sounding rhetorical or pointless
