I saw it and thought it was boring. The only interesting thing I learned was about the "lemon dance" and the "turkey trot". We don't have anything like that in NJ because all of our districts have local school boards. Each school is stuck with it's own lemons (unless they make their lives miserable and force them to quit).
A more interesting movie about the education system is called "The Cartel". It deals mostly with NJ schools, but covers a broader range of issues besides teacher's unions, such as safety, over- regulations, corruption, etc.
Both movies are pro-voucher, but I thought Superman was a bit too simplistic.
repost: Wish I had time to write the stories my wife told me just this week about parent excuses and American student's laziness. Baffling for sure, but telling of why we are growing dumber and dumber as a nation. Oh, by the way, turn on TV too if you want to understand our culture of narcissistic insanity, detective shows, and medical aliments that House can't solve. Then watch Repo shows and whatnot on TruTV for a interesting view of your fellow citizens. Abandon ship, abandon ship!
