Ghibli, it's the only one that combines wonderful storys and perfect drawing art. And what I always see, the only one where foreground and background is high quality and one. In most animation films or series, you always see, wich piece will move next, the animated parts hve other strucure, they don't fit into the whole picture.
Pixar is funny with its computer animated comedy, but not even close to ghibli's quality.
And Disney? No Art, the animation and drawing ist just for children, compared to ghibli movies it seems just cheap.
