I watched this anime 2 years ago. Hayao Miziyaki is a renowned anime artist and is one of, if not, top animators in Japan. He was behind this anime. I have watched all his work and all were amazing. Ponyo is Japan's answer to America's Disney "The Little Mermaid." A great animated film for kids and adults.
Very cute. Amazing underwater scenes and magical storyline. Suitable for very young children. Cons: If you're looking for a rational plot, you may come away from Ponyo disappointed. Horrible auto-tuned theme song in closing credits of English dub.
