100 Nights of Hero is one of those films that looks interesting on paper—female solidarity! Fairy-tale aesthetics! Subverting patriarchal tropes!—but lands as a niche art piece that most families will skip entirely.

The core premise (neglectful husband, charming interloper, devoted maid protecting innocent bride) sounds like it could be empowering, but it's wrapped in enough mature relationship dynamics that it's really only appropriate for older teens and adults. And even then, the mixed reviews suggest it doesn't fully deliver on its promise.

For parents: this isn't a hidden gem you'll want to share with your 13-year-old. It's more of a 'maybe I'll watch this alone after the kids are in bed if I'm in the mood for something slow and stylized' situation. The 6.2 IMDb tells you everything—it's fine, but not compelling enough to overcome the mature themes and art-house pacing.

If you're looking for stories about female friendship and resistance to patriarchy that your teens can actually watch, try Ladybird, Little Women (2019), or even The Handmaid's Tale if they're old enough. This one's too obscure and underwhelming to recommend broadly.
