see I think Andalites would have the same disdain for human culture that you have for "low-brow" culture.
I mean, it's never explicitly talked about, but I'm pretty sure Andalites have their own literature, music, etc. I don't think they have theater b/c Ax says something typically ignorant and amazed about actors, but they definitely have stories, because we know they accepted the Ellimist myth into their collective unconscious. So if Steven Spielberg or David Lynch or, I don't know, think of any highbrow director (lol Roman Polanski?), came up to an Andalite and was like "I really think the themes about resurrection and rebirth in my new film will affect a space-faring race like yourselves," I think they'd laugh in his face.
Or else, you'd have Andalite academic types going all "yes, humans have finally entered their proto-enlightened phase, let's watch how long it takes for them to catch up to us intellectually," so there may be some interest.
