I have found the show to be introducing a somewhat TABOO subject to the general population in a dramatic format, slipping little bits of practical information in here and there, much as a Dean Ing novel (ie: You will Survive Doomsday) does. It IS too little, too late, but anything that gets the general population to wake up from their "zombie-like stupor" is, to me, a positive contribution to the American society, at large.
