Query: A Terrifying Must See

This film was very watchable. It was well produced, informative without being preachy. It does not condemn drilling for gas. Or tell us to kick the energy habit. It shows us the dangers of removing legislation that was once in place, which would have forced corporations to drill gas safely. It stresses that without regulation corporations will always seek the cheapest/fastest route.
