“Should a film confuse the viewer? Only if there’s a feeling of ‘reassurance’.
Should a film leave unanswered questions for the audience? Only if it’s intentional. How many would-be great films have been ruined by the refusal to ensure that the audience understands what they need to understand? Any unanswered questions, then, are best clarified to the audience as ‘something you don’t need to know’. Otherwise, you don’t have ‘ambiguity’. You have confusion.”
