I've seen the R2 version, and was blown away. Sure, we're talking a 20 year old animation here, but the story and characters are marvellous. We may not have state of the art CG dodads flying at us, but the quality, and the creators involved are first rate all the way.
The R2 disc featured comments by Kazuyoshi Katayama, a production assistant, later responsible for "The Big O", "Appleseed", and "Argento-soma." It also features the legendary Hideaki Anno. A Key Animator, who designed the Giant Robots for Miyazaki. Anno is, of course, famous for directing "Nadia, Secret of Blue Water", "Wings of Honneamise" and his claim to fame, "Neon Genesis Evangelion."
The music is by Joe Hisaishi, and it has touches that bring to mind things he does later in "Castle in the Sky", "Princess Mononoke" and "Spirited Away." The music was done under tight budget constraints, so they seem to have used a lot of synthesizers. But hey, it's the 80's, so it's understandable. Overall, a must have DVD by one of the great artists of our time, with a veritable who's who of anime supporting him. "Nausicaa" is a wonderful look at Hayao Miyazaki's genius, so obvious in this, his first original film. I would also suggest the Graphic Novels. It took Miyazaki 12 years complete the tale he touches on in "Nausicaa". His true masterpiece.
