This review will sound somewhat personal because of my sincere interest and involvement in the subject matter: I took part in an Ayahuasca Weekend (3 ceremonies) with shamans trained in Peru by Ricardo Amaringo and I also frequently use my own plant mix in a smokable blend (including a famous tryptamine dubbed "The Spirit Molecule" ;) ) that contains Ayahuasca leaves, mullein and cannabis.
Therefore, although my experiences with actual trained shamans are very few, I claim to know a bit about such Altered States of Consciousness.
With that being said, it becomes obvious that the negative reviews written before this one are akin to people who are virgins discussing the pro's and con's of Sex, if you catch my drift ;-)
To claim that using such psychoactive substances is "to fool yourself"... well... is TO FOOL YOURSELF indeed !
The very point of those psychedelics (check the etymology of that term, btw) is that they dissolve sub-conscious barriers and personality structures to confront your own "Deeper Truths", to see Who and What You truly IS.
There is an increasing body of scientific evidence that explain simply and elegantly HOW and WHY Ayahuasca and other traditional plant remedies WORK (not on ALL cases, but on many !). One only needs to NOT BE close-minded about it (...) and do proper research ;-) It is related to the limbic system, allostatic load, and so on.
So, to talk a bit about the film itself, although it is not perfect, I found that it was apparently a sincere effort with notable qualities.
I recommended it to plant medicine lovers and skeptics alike, even though it is very clear that such topics are very hard to apprehend without a personal experience.
Which explains the obvious polarity in the reviews on different sites...
Overall recommended, especially as it is not excessively long.
