Building walls along lines on the map is the perfect way to do politics by managing fears. That is why the fairy tale about the Great Defensive Wall On The Border is still told and still eagerly listened to. This film is an expression of anxiety about living in a restricted space. High walls with musty air inside - it is easy to suffocate in an airtight container. The more the wall protects me, the more I feel trapped. Surrounded from the inside.
