It's wildly original, imaginative, unpredictable, and creative. It's also eccentric, dark, and eerie. Some elements are inexplicable, others are gratuitous. It's the only animated feature that I consider as good as Spirited Away. I enjoyed Finding Nemo much more than I expected, but it was too formulaic and technologically based for me. The Triplets and Spirited Away use technology with more forbearance and always subordinate it to artistry. I've attended movies with deeper bass, wider dynamic range, and more spectacular spatial effects, but I don't know of any movie with better overall sound.
