Waiting for Superman (a documentary on education in America)

I just watched the trailer for this movie about the education system in America and how it is oftentimes broken.  This is a documentary about a nation that claims to leave no child behind, but seems to be doing so at an alarming rate despite politician's promises to do otherwise.  The movie comes out on September 24.  I'll be seeing this one.  Here's the link for the trailer:
