I saw it, and thought it was good, but it brought home to me how lifestyles like this can seem romantic and all about freedom, but the reality is precarious and often dangerous.
I would hate it.
I thought the Fern character was interesting. She was 'untypical' before she took to the road, and had only settled down in the first place because of her love for her husband, but it also struck me how sad it was that after years of working as a teacher and in HR she was considered unemployable because of her age, and how quickly people can go from relative security and status to nothing when there is no safety net.
I watched it with friends, and we also drew parallels with the dustbowl era, but felt that there was a difference between the way in which people like Woody Guthrie (and to some extent the young Bob Dylan) were portrayed - more footloose than homeless, and the way the people in the film had little or no choice but to live as they did.
I liked the docudrama format, and the way they used actual nomads to tell their stories.
