This movie is frustrating. It treats all of the "experts" equally. There are dowsers, psychics, housewives, crop researchers Living in Los Angeles who have never seen a crop circle, sensitives, flakes of every description... They spout their woo about vibrations, emanations, psychic connections with aliens, military conspiracy theories...
It is done in the Erich von Däniken style: could this be a time warp to another dimension? Could crop circles cure AIDS? I tease, but they spin endless bullshit without any evidence.
They talk about there being "electric fields" inside the crop circles. But they never got anyone with any credentials to measure them or say what they meant. They could easily have meant "magnetic fields". Nobody in the whole movie seemed have more than a sixth grade science education.
Because they have so many flakes, and people with crop circle tourism businesses babbling on, you never know who is putting you on. You can't trust a thing anybody in the movie says. The movie intends to hard sell you on woo. It makes no attempt to give a balanced picture.
I consider crop circles a form of art. What puzzles me is the exquisite quality of most of them. Usually public graffiti is dreadful. I am also puzzled that nobody has managed to get photos of a partially complete crop circle. Surely automatic IR cameras should have caught someone. There are claims of various features of the crop circles being of superior quality to clearly man made ones. For me to believe that, I need someone with reliable credentials. Since we don't have that, I suspect that is just nonsense to reel in the tourists.
Unfortunately, there are not that many aerial photos of the crop circles. They are not nearly as impressive from the ground.
