Seasons 1 and 2 were novel and intriguing and drew me into a unique and actually plausible possibility of a US catastrophe. I do not know the reasons for ABC cancellation but I found, after watching Season 3, very good reasons why I did not appreciate any of Season 3 and, most likely will not waste my time on Season 4, if it continues in its current scripted path. It should have ended after Season 2 with the success of the US system of government and a man who met his challenges--after all that was all it was suppose to be about. Instead, its greedy success produced nothing but an afternoon of soap operas as if this was White House Desperate Housewives. Every conceivable thing you could think about was lumped into this Season 3, illegal immigration, gay rights, transgender, election fraud, assisted suicide, classic woman in distress literally running into bed for sex just because she is a woman, a hint at pregnancy, bioterrorism, Russian military, classic big screen military intervention in the situation room and finally a stamp of progressive/koombayah over all of it--you name it, it is all there and it all seemed to be done so that they got it all into the Season 3 even though the initial plot here has nothing to with any of this.
