When it comes to film, I'm rather keen on the first-person narrative approach. Many documentaries mix in first-person narration with a "voice of God" narrator who serves as a kind of guide and voice of authority on a journey of discovery. There is nothing wrong with that, but for short films, telling a story with only powerful visuals and first-person narration can be very effective for providing an emotional, insightful POV. The short film below is another good example of an amazing story of resilience and determination told with only first-person interviews. The film is called "Alone in the Zone" and is the story of one farmer, Naoto Matsumura, who remained behind in the ghost town of Tomioka inside the Fukushima evacuation zone in spite of high levels of radiation and loneliness to attend to his abandoned animals. The film also introduces Kenji Hasegawa's who was evacuated due to high levels of radiation and for a time sought refuge in temporary housing. Both men share candid and heartbreaking insights into their lives as well as their views of the nuclear power industry in Japan, government inaction and daily life in an area with high levels radioactivity.
