Mirai is genuinely beautiful—a meditative, visually stunning exploration of sibling rivalry wrapped in magical realism. It's emotionally sophisticated in ways most kids' movies aren't, showing a four-year-old's jealousy and rage without sugar-coating it, then gradually revealing how empathy and family connection can transform those feelings.

But let's be real: this will bore a lot of kids. It's slow. There's minimal dialogue. The fantasy sequences are more dreamlike than plot-driven. And that train station scene? Actually frightening in a way that's intentional but intense.

If you have a thoughtful kid who's struggled with a new sibling, or who loves anime and can handle contemplative storytelling, this is genuinely special. If you have a kid who needs constant action or gets scared easily, skip it. The 80% audience score (versus 91% critics) tells you everything—this is more art film than crowd-pleaser.
