I occasionally watch these types of shows just to satisfy my 'love to hate' certain things, like the complete idiots that subscribe to aliens and ghosts and the like. Crop circles have pretty much been debunked, and a lot of the crop 'artists' have come forward just to say 'gotcha!'. I find it odd that years ago crop circles were just that, circles. Now they are, of course, displaying "awesome examples of complexity", OBVIOUSLY alien. Whatever, crop artists are just getting more experienced and/or bored with the ordinary. Those who argue that the 'circles' are real are either profit minded (selling books or movies), stupid rednecks (whatever country they originate), or delusional (drugs, alcohol, or mental issues).

If all those facts are true we see on 12/21/2012 simple like that. If aliens coming to this planet my gun are waiting and for sure first I shot and later I ask. if they are real i don't think they coming in peace, when some one are authentic are not hiding on the darkness of time.

@ Elisha Cooper--- if making intricate, complicated Crop Circles is so easy, let's see you do it.
As for others who have commented, I'm not going to try to convince anyone, one way or the other, as to the authenticity of the theories put forth in this documentary. I believe what I believe. There is less than a year until the date specified, ( 2012-12-21 ) so it's possible that we will all still be around to find out the truth of the theories discussed here. I'm taking a wait and see stance, myself.
However, ( you knew there would be a "however" ) I'm sure I'm not alone in thinking, it would be so much easier to convince others that you are actually thinking about this topic, if you could find it in yourself to LEARN TO SPELL AND USE PUNCTUATION PROPERLY. If you could do that, many of us would find it so much easier to lend credence to your rantings.I'll give the show a '5', and watch it again.
