Once Upon a Time... Planet Earth Ratings & Reviews

RichyEOctober 18, 2025

Saw this one as an adult. Same Maestro, same crew, but now they’re talking climate change, water scarcity and global inequality. It’s like the series grew up with me. Still charming, still educational, but now with real world urgency. Animation’s familiar, music still hits and the tone? Gentle but firm. No panic, just “here’s what’s wrong, here’s what we can do.” Watched it knowing full well the planet’s on fire. Felt like a warm reminder that learning never stops and that cartoons can still teach grown ups something.
