Raw A really good idea and I thought of "Walking The Camino" as I watched.
The changing train locations and directions had me scratching my head, so I think the editing & sequencing could have undermined the appeal a little. Perhaps some narration or at least some text may have helped to link the passages.
I loved the scenery, it was raw, wild and beautiful, like some of the people. Perhaps a little music would have added mood.
Some interesting stories, but not enough variety for me and too few people had any real depth. Not a very long film, so I felt a little short- changed.
