One of the reviewers claims to have worked in medical "settings" in one form or another for many years. She(?) is also in awe of this movie and it is not difficult to understand why. She tells us. She has endured and still is enduring the traumatizing personal drama that is to face death. Her words also tell us what is cruelly wrong about this documentary.
First of all, modern science is fundamentally different from "traditional" healing in that it removes randomness by means of the scientific process. If acupuncture (or whatever other "traditional" practice) is ever considered to have merit in modern medicine, it is because it will have been tested formally, with rigor, and found to deliver specific outcomes. Furthermore, were acupuncture ever to be found able for (again) specific purposes, it would not show that "traditional" medicine was right all along. It would simply show that modern medicine is able to separate fact from fiction... to everyone's benefit.
Second, there are many afflictions (e.g. appendicitis) that modern medicine cures routinely even though they were deadly until only a few decades ago. Our grandparents saw their peer die for comparatively very little. The forest was always there, the wizards and incantations were always there, acupuncture was always there, and so were the corpses.
Are there limits to science? Evidently.
Are there faults on how those of us in modern societies participate in the medical establishment, whether as practitioners or patients? Absolutely.
Is it consequently the case that we should turn to voodoo when we are faced with a disease that forces us to prepare for the most frightening journey? Clearly not. It is repugnant to even suggest it because it reveals a desire to profit from despair.
And this is what this documentary shows. Desperate people being taken advantage of when they are most vulnerable.
