I remember finding a
horribly edited version of Nausicaa when I was a kid in a video store. I had no idea at the time it was edited and thought it was just amazing! When I saw that it was coming out on DVD a few years back, in it's original unedited version, I didn't think twice about buying it!
Spirited Away and Princess Mononoke also get a big thumbs up from me. I still need to see others that are on that list, though.
