This is Extruded Cartoon Product. Its blurb sounds like a blender of modern cartoon cliches: Post-apocalyptic! Female protagonist! “Journey home” plot! Power of friendship! Giant talking animals! Secret tragic villain backstory! But it doesn’t actually do anything with it. The whole thing has a very design-by-committee feel to it — it’s just woke enough to make the Tumblr crowd spread it like wildfire, without being truly transgressive or subversive.
