It's because the art world has flat-lined and become an echo chamber of received opinion and toxic over-praise.
So she's railing against over-praise by... over-praising something. Maybe there's genius in that, but I think she believes she is being deep, which is ironic, and doubly so when you read what she said just prior to that:
There's too much gimmickry and irony and not enough intuition and emotion.
Gimmickry? I'm not sure it's possible that he could have included any more in the movie (everything from "gimmicky" CGI to story gimmick - I mean come on, Anakin BUILT the two 'droids? Really? It's a big fuckin' galaxy, I ain't buyin' it. And yes I know, that reveal wasn't in THIS film, but still...). Irony? Well, not only is her choice ironic considering WHY she says she chose it, but the irony of Lucas eschewing his younger self's statement that (paraphrasing here) technology should not win out over humanity is a most perfect example of the meaning of the word. And if she was looking for emotion, boy did she pick something with an overdose.
Fast, cheap, good: pick two.
