This "docu-drama" contained more political statements than a French feminist melodrama. OK, I admit I exaggerate but if you want to make a documentary you have to consider all possible angles and not be a servant to your own point of view. This is not a documentary. It is Ken Burns world view about the dust bowl. Don't look for reasonable explanations about the causes and circumstances in which the event occurred. It like one of those zombie movies, you know the ones which starts like, "its the year 2137, there has been a deadly virus attack and only few humans survive and the rest have turned to zombies". You know this is not a real story yet they put enough real circumstances in it for you to be engaged. This is the zombie movie of documentaries.
