A classic. Bought it as a gift to a friend who kept on wanting to visit for play dates to watch the movie. Think its a wonderful way to introduce children to the world outside Pixar/Disney. My oldest visited Japan this year all thanks to Master Miyazaki.
This is an amazing Anime film, but that is a secondary factor. It's like a fairy tale but with a giant cat-troll-thing. My girlfriend loves it. It's well drawn and animated and has held up to the test of time. It's accessible to everyone even if you're not into anime generally.
