This brief experimental documentary about the migration crisis comes from Italian artists and film-makers Maria Iorio and Raphaël Cuomo and is a collage of unused footage from video pieces they have made together over the past 15 years. It’s a film with interesting things to say about the fortressing of Europe during that time,and the hardening of policies against migrants and asylum seekers. But I confess to finding it hard going and slightly frustrating. By the end I wondered if it might not have worked better as a gallery installation alongside the duo’s earlier works.
