You missed nothing. It was a drama with little to no fact. I turned it off 20 minutes from the end. I could not take it any more. A really stupid show, poorly done.
What was not factual about it? You saw that they were using archival footage from Katrina, a big fire in NJ after Sandy, Occupy Wall Street protests, etc., including Pres. Obama telling people to remain calm and to obey the instructions of government officials on the scene.
