I didn't like it
I like indie films, was once an indie documentary film producer myself in the 70s, but I found "Off the Map" depressing, cliche ridden and self indulgent.
Also it seemed to promote not taking responsibility for your actions. When the girl was asking for the social security number and bank account number I did not understand until she came up with a mastercharge card, I assume she used his financial info to qualify for it. Then she saddled her parents with a 4000 dollar debt.
All of the posters say that the family was completely in touch with the universe in tune with nature but that is just not true.The family relied very heavily upon one man who had a "straight" job and lifestyle. Only the mother seemed to really be in the "in tune with nature" mode. The father was nearly catatonic with depression, and the daughter could not wait to escape that "organic" isolated life.
Humans are social animals..I prefer films which show how people can live completely well adjusted lives in urban surroundings with intellectually stimulating exchanges and who pursue all kinds of creative and or political endeavors, to me that is just as healthy as the granola lifestyle without indoor plumbing.
