Coo is a story about a young boy who lives on an island in the
Pacific with his father. He finds an animal stranded on a beach, only
to find it's a sea-dwelling baby dinosaur. Some say it's like "Free
Willy" (that movie about a killer whale) with a dinosaur, but the story
has an "ecology" theme.
The art is cute (your heart will melt when you see Coo, the dinosaur),
but it's not recommended for young children due to very violent scenes
where animals get shot at. (Sumire-chan cried in certain scenes)
Good art and animation, good translation and subtitles.
