My statement was not supposed to be an insult. Ghibli movies always have certain things in common. The animation is the most obvious, but the stories also have a certain air to them. This is very different from what you will observe in other anime. Similarly, Disney feature films at least have a very different feel to them than you will find in some other western animation. Automatically taking this as a judgement of quality goes besides my actual point.
Either way, as we are comparing quality now, apparently: You all are very familiar with the Disney tropes and clichees, and obviously they annoy you. But has it never occured to anyone here that some people who grew up with Ghibli might find its recurring topics, twists and style just as tiring? That for some people, Disney is a fresh and unexpected deviation? Totoro and Kingdom of the cats being implausible non-stories is excused with magic and wonder here, but the all-too-obvious morals and a black-and-white morality kill Disney movies? I don't think it's a fair comparison if you give something bonus points just for it being new to you. Ghibli movies are not perfect. They don't have the same shortcomings as Disney movies, but they do have shortcomings.
That said, I think it's perfectly fair to say "I don't like Disney movies as much because they can never surprise me.". But that's something else.
