From my own research and investigation over a period of many years as an alien researcher and spiritual medium (a unique combination), I find that there are a few errors in the film's analysis. Like the idea that the aliens can take our consciousness out of our body and then put it back in again. That is a belief derived from brainwashed abductees. To be able to control astral projections involves energies that cannot be manifested with physical machines and the aliens, who are not spiritually based, do not have that capability.
Another error is the idea that the Greys are automatons or robotic and do not have souls - which I also believe to be untrue. They are very intelligent, mechanistic in focus, spiritually indifferent, parasitic beings. Despite their spiritual retardation and belief that Science Is God, they do have souls and are not robots.
However, the documentary is spot on about New Age proponent, Dr. Steven Greer, in that he completely ignores the abundant physical (e.g., implant and close encounter related illnesses) and abundant anecdotal evidence and espouses that the aliens are our benevolent space brothers! Some even believe that he is a governmental disinformation agent.
One of the outstanding researchers and authors on this topic, Dr. Karla Turner, is also addressed. She was harrassed and eventually threatened to stop teaching. Her subsequent death from a rapid form of cancer is highly suspect; she was likely murdered by federal agents because she was too accurate in her appraisals.
