Watched Ponyo earlier today and I enjoyed it much more than I was expecting. The room I was in had about 50 or so people. Not bad for a showing at 11:00 am on a rainy day.Judging from the trailer and reviews I'd read, I had expected this to be very kid-oriented and I wasn't wrong, but it managed to make me watch it through a child's eyes and admire the simplicity of it all. The plot wanders slightly aimlessly, making it the movie seem longer than its 84 minute run. But, the animation is nothing less than breathtaking. The amount of detail that's poured into every shot of the water and the different type of fish and crustaceans is just astounding. The music is sublime, providing the perfect atmosphere to lay back and watch the world of Ponyo.
Dub-wise, this is easily the best dub for a Miyazaki movie that I've heard ( I have to say that I still haven't seen Totoro). Aside from the ending song- which sounds just like what you'd expect from a pair of kids singing- Frankie Jonas and Noah Cyrus put up solid performances in their respective roles. And yes, Tina Fey deserves all the praise she's been getting for her role as Lisa.
All in all, Ponyo is a quintessential children's fairy tale. Don't go in expecting something as hard-hitting as Princess Mononoke and you won't be disappointed.
