I have done ayahuasca many times and have found it always to be a beautiful, life-changing experience. Making a true film about the ayahuasca experience would have made a better film, but no; this film had to take a potentially beautiful experience and toss in a demon named Manohin (he actually named himself early on in the film, but nobody present seemed to be paying any attention to this fact, so a lot of time was wasted asking the demon what his name was), and the chaos that ensues while under the influence would be insurmountable for the heroine. Take OUT the references to ayahuasca, and it would stand alone as a good horror film.
