1975 written by Terry Nation of Dr. Who fame. Chinese super-flu breaks out, spreads across the world at airports, within a few weeks 99% of the population is dead and the random survivors are trying figure out how to live without modern civilization. Spends 4 seasons exploring the different political and economic systems and how little we know as individuals for survival. Basically The Walking Dead without zombies, or Day of the Triffids without Triffids. Bonus: Sorta topical too. Anyone else ever watch this? Low budget and slow, but miles better than modern PC ADD TV to me.
