Yep.
Those older movies are beautiful achievements for sure. But it's disingenuous to say that there isn't a plethora of movies and shows today that rival and surpass those older examples visually. Not to speak of just how much more fluent animation has become.
Many of the people who worked on those older masterpieces are still in animation today, and have only become better at their art.
I guess it's a matter of taste then. I really enjoy the vibrancy and fluidity of animation we get today. And I find them to be no less expressive.
