Query: Teachers: don't bother with this one

Just wanted to echo the earlier review... fortunately I didn't pay anything for this video; it was given to me. Still, it's not worth the price. Not only is it deadly dull and the talking heads overly pretentionous, but the piano music is the most annoying background music I've ever heard in a documentary. I wouldn't even think about showing this to my high school students.
