These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Nausicaš of the Valley of the Wind
Adaptation Displacement: To many a Studio Ghibli fan, it's fairly unknown that there even is a manga of Nausicaš. Although the movie is really just a 2-hour compression of the first quarter of the manga.
Anvilicious: Of the Green Aesop variety, mostly for the film though. It gets a bit more complicated, if not somewhat subverted towards the end of the manga. Specifically, the question of whether or not the Master Computer's plan to artificially restore Earth's old ecology is just as bad as the callous environmental destruction that preceded it, since it would mean the deaths of the countless biotechnological creatures (including "Humans") who have made a life for themselves in the new world.
Nausicaš herself is much colder and dire than in the movie, fitting for the manga's more nihilistic tone.
Broken Base: Despite being uncut and more accurate, Disney's dub of Nausicaš still has its share of harsh detractors, with some declaring that it still fails to do justice to the original Japanese. You'll have to decide for yourself if you like it or not.
Fans tend to be split over the manga. Some consider it to be a vastly superior story to the movie; others think the plot gets too muddled and self-indulgent in the later volumes and prefer the movie's Adaptation Distillation.
Escapist Character: Nausicaš. Who wouldn't want to fly around the world in a miniature aircraft, exploring beautiful forbidden lands?
Jerkass Woobie: Possibly a number of characters, but perhaps most notably Kushana. Introduced in the film version as a seemingly stereotypical evil queen ("Nice valley. Think I'll keep it."), her status as an apparent Card-Carrying Villain is quickly subverted. This apparently was deliberate on the part of the writers: Miyazaki describes Nausicaš and Kushana as "two sides of the same coin", largely differing in that Kushana has "deep, physical wounds".
Les Yay: Nausicaa and Kushana have some of this going for them as Kushana seems to take a bit of a shine to Nausicaa as the story progresses.
Macekre: Warriors of the Wind again. The incident is why all Studio Ghibli licenses contractually stipulate that not a frame of animation is to be changed or cut (with the obvious exception of replacing the credits).
Mary Sue: Nausicaa. Probably in both the anime and the manga, but moreso in the manga. She's pure and good, has a rapport with nature and the Ohmu that no one else has, she can ride the wind like no one else can. Everybody seems to love her and the few people that don't either eventually come around or die out of plot necessity. The only flaw she really seems to have is a slight temper/murderous rage which she seems to overcome very early in both versions.
Squick: Film-only example. When Kushana takes off her glove to show that she no longer has an arm and then says "Whatever lucky man becomes my husband shall see far worse than that." Ew.
She retains the armor on both her legs after taking off her armor, too.
Note that in the original manga, Kushana appears to be 100% whole (she retains her arms and legs in any case).
Tear Jerker: Nausicaa flying straight into a Pejite flying machine, standing on her glider, her arms outstretched always makes this troper choke up. They're shooting at her and she still believes they won't kill a defenseless girl. In the world she lives in, that kind of faith in people is touching as hell.
Word of Miyazaki states that Nausicaš's resurrection near the end of the movie was not meant to be analogous to Jesus and that he would have changed it if somebody had pointed out the similarities before the film came out (Miyazaki is many things, religious is not one of them).
