It’s slightly attenuated at a perhaps overly dreamy two hours.

But this modern-day Romeo and Juliet tale, based on recent events and embellished with near-magical moviemaking skill, earns its keep by caring so much about the innocent human beings caught up in relentless Mafia vendettas. Thirteen-year-old Giuseppe is the high-school cool kid until his dad agrees to testify against Sicilian mobsters. When he’s kidnapped in order to silence the old man, almost-girlfriend Luna is the only classmate who keeps querying where he’s gone. Good thing she’s as kickass as any Chloë Grace Moretz character, because what she’s up against is disturbingly dark and murky, but also fablelike in its youthful certainties.
