Very good points.
And the characters are not communicating very much. They seem distant to each other. There seems to be little real connection going on.
At the end she went to the garage and he went to the roof is an example.
I definitely don’t pay attention to this show like I do The Walking Dead.
This is similar to the story told in TWD. Rick wakes up, from a coma, and finds the world far different than when he was last awake. The episodes follow his story. He and the other characters didn’t know about the ZA or how it started or what to do to kill them, etc. Seasons 1 and 2 played out and we the audience find out more as the characters do, etc.
This is the same thing just from the beginning for this family rather than from when the main character wakes up from his coma.
