In a way Eli Roth's "The Green Inferno" (2013) is the evil and even more apocalyptical twin to this film. If you are dreaming of a life in seclusion and harmony watch both films at once or after one another. Yes, ethnographical interests often end in death and destruction. Paradise lost. And Ti West's "The Sacrament"(2013) is a really good, deadly seriously and uncanny mockumentary about Jonestown. Back to nature and back to the spirit are equally self-destructive movements.
