The Secret of Dr. Grinberg

"The Secret of Doctor Grinberg (El secreto del doctor Grinberg) is a documentary that, as the name suggests, focuses on the Mexican psychologist and neurophysiologist Jacobo Grinberg, who has been mysteriously missing since 1994. He was a controversial figure known for his pioneering studies in diverse fields such as parapsychology, shamanism, telepathy, and meditation. The documentary does not provide definitive answers about Grinberg's enigmatic figure but revels in his mystery with a certain air of sensationalism. In itself, it may seem exploitative and even absurd, but as an approach to the myth of a character with his own aura of mysticism, it is a great documentary."
