The only reason people suck off Ghibli is because it's hyper-animated and hyper-detailed. Beyond a purely technical standpoint, Ghibli is overrated as fuck. Even as a kid I didn't like it because the characters moved in a disgusting uncanny way.
But Westerners aren't entirely incapable of artistic animation. If The Black Cauldron wasn't censored and followed the books better, it would have been pretty based. Other examples include Watership Down, Plague Dogs, When the Wind Blows, Pink Floyd's The Wall, etc.
Not only do these movies have appealing animation/aesthetics, but the writing is good too.
