Mistrust porn
This show seems to be an accumulation of short sequences about the breakdown and impossibility of trust after a recent social/societal upheaval.
Conceptually, it's like a "super lean" version of Games of Thrones - with all the drama and sex and meaningful (or not) relationships expunged - where absolutely every single character dies, it is almost impossible to judge a person's true intentions, and where trust is usually fatal.
The show is probably too smart to be too obvious about it, but one wonders if the zombie plague in this doesn't somewhat echo the revolution that social media introduced (for better or worse) in our lives...
Quite on point in fact, and absolutely of its time... so I guess it does capture some fundamental truth about our epoch (as genuine works of art -whether popular or not- should strive to do).
