Older animation is always more appealing to me because they were aware that they were animating a cartoon. Now, they're so obsessed with hyperrealism. No, I don't need to see the character's individual eyelashes or their pulse; just make it look like a well-made cartoon.
It is such a perfect send off to Luke Skywalker. He halts an entire army with the mere image of his ideal Jedi form and wins the day completely nonviolently.
An absolutely brilliant Luke moment.
