I haven't given Nausicaa nearly enough love on this site.
This movie is strikingly beautiful. The artistry is amazing, surpassing both the entrenched conventions of American animation and traditional anime.
One should also bear in mind that "Nausicaa" was made in the '80s during a time when Disney was churning out stuff like "The Black Cauldron" and "Oliver and Company," (although I am quite fond of this latter film) and, quite frankly, not doing so hot—at least not until they released "The Little Mermaid" (plus that whole deal with Michael Eisner selling his soul to Satan, of course).
Furthermore, nobody creates heroines better than Miyazaki, and the eponymous Nausicaa sets the high mark against which all other heroines are measured. Fearless, beautiful, and deeply empathic, Nausicaa is an infinitely better role model for impressionable little girls than our dear Ariel, a kid who banked on the theory that "the men up there don't like a lot of blather." (Although in Ariel's defense, this theory does have merit at times.)
