Miyazaki's films fall under many of the trappings and cliches that anime films always do, the only way in which he could be one of the few anime directors to be considered to be making real films is that he's mainstream enough. Since his films also fall under most of the trappings that children's films do, like Snow White or Toy Story, then he could be considered to be a children's film director, which is little different in status to an anime film director.
I understand that the man is a great and important director but his work definitely has an age restriction on it, while some of his work like Kiki's Delivery Service or Princess Mononoke are I have found touching, other's have left me cold, like Howl's Moving Castle. For the most part I can see where they are coming from, but I can't appreciate it, because it really does depend on who you are and in what point in you're life you are watching them.
And its a pretty bold statement to say that while excluding Satoshi Kon when Perfect Blue was originally intended to be a Live Action film.
