Guide a user from a film title, scattered feelings, difficult-to-explain reactions, or messy notes to a coherent first-person Chinese reflection, movie review, or film essay. Use when Codex needs to help someone think through or understand a movie after watching it by asking staged, interview-led questions, drilling into scene-level details, extracting user-owned viewpoints, pressure-testing interpretations, and drafting polished prose instead of generic plot-summary content. Especially useful for art-house, ambiguous, or hard-to-parse films where the user needs patient guidance before writing or before arriving at any stable interpretation.
