I didn't read them in installments, though; I read by season when they were offered on NetGalley.

Survivors of an apocalyptic event struggle with the loss of their families and the terrifying creatures that roam a landscape now curiously devoid of life. Multiple characters in various locations must re-evaluate their world when at 2:15 AM on Oct. 15, almost everyone vanished.
There are the good, the bad, and the hideous.
Entertaining, sometimes offensive, and weird.

Yesterday's Gone (Season Two)
While I found the first season entertaining, I found season two much less so. The connection to season one was confusing, Boricio's role is simply abhorrent even with a twist at the end, too much violence, too little character development, and the plot becomes more complicated, not more complex (a considerable difference).
There are six seasons published so far, and I may read another season if offered on NetGalley, but I'm no longer really curious about what happens.
