Themes and resonance At its core, Zero meditates on loss, identity, and the ordinary mechanics of moving forward. It’s less interested in definitive answers than in the messy process of adaptation. The film asks: what does “zero” mean for the self — an erasure, a fresh start, or a neutral ground where things can be rebuilt? That ambiguity is its strength; the unanswered questions linger, allowing viewers to bring their own histories to the frame.
