I've heard good things about both the Manga and the Show, but haven't even got around to reading or watching it myself.
If it does the problematic herbivore/carnivore = gender/race shit that Zootopia did then I'll pass. (Do none of these writers understand that omnivores and big aggressive herbivores exist?)
Just talking about the predator/prey dynamic, it's certainly problematized, but in an ambiguous and multifaceted way. It's not an allegory for any one social phenomenon in particular. It's a dynamic that reflects various social phenomena and divisions, but it doesn't map cleanly to any one thing in specific. I think it's this lack of straightforward allegory that makes the show interesting, and basically purely up to interpretation. The show is good, but it is weird and I think it'll make most viewers uncomfortable at various points.
