Let's be real: this is a niche show. If your teen is into DOTA 2 or dark fantasy anime, they'll probably love it. If not, they'll bounce off it immediately.
The animation is gorgeous and the world-building is solid, but it's violent, bloody, and thematically heavy. This isn't Avatar: The Last Airbender—it's closer to Castlevania or The Witcher in animated form. The IMDb 7.7 tells you it's competently made, but that Common Sense Media 15+ rating is spot-on.
For parents: if your 15-17 year old is asking to watch this, they can probably handle it if they're into anime and fantasy. But don't let your 10-year-old stumble onto it thinking 'oh, it's a cartoon!' This is absolutely not for kids, and honestly, even many teens will find it too dark or just not interesting if they're not already into the genre.
Bottom line: good for its specific audience, but that audience is pretty narrow.
