I am not sure
my attention wandered during the show.
There may have been a segment of MIT students debunking the circles but most of the feature was definitely pro-circles and it seemed to well done. One of the things that caught my attention was the comparison of circle designs to various earthly artifacts
I must admit that I have no particular interest in explaining the circles. I am content to wait for little green men (or women) to land on my lawn and explain.
Whoever does them they are beautifully done and have attained art form status.
