I'd have to see this thing to make a completely accurate assesment, but at this point, one thing that comes to mind was the massive blackout in the NE a while ago. With that massive of a blackout, you would expect chaos, looting, disaster, etc. in NY city, Boston, etc. However, absolutely none of that happened. People remained calm. This occurance goes directly against what the producers of Oil Storm are saying. So, based on ACTUAL events, I would say people would remain much more calm and collected than what that movie portrays (or so I perceive it portrays from the previews). I think most Americans can work together when a big problem/disaster arises much better than what many people think. So, don't think that can't happen in the future.
