I found it *boring*. "Fear the Snoring Dead" kind of boring.
They spent a whole lot of time developing the characters around a core conflict that will shortly cease to be an issue. This core conflict developed painfully slowly, and in a way that left me not really caring much about any of the characters in question. All of this could have been handled as post-facto exposition.
I tuned in to see the beginning of a zombie plague, and they gave me the family melodrama around a young man's drug problem. While that may be a good story to tell, this was not the place for it.
I imagine they thought it would be good story telling. But it's predictable.
The kid will do stupid things to get a fix. sell somebody out, take unreasonable risks, disappear for stupid reasons so the family has to go look for him.
Then he'll get doped up stupid, and that'll be another liability situation.
Then he'll try to go straight and get withdrawal. I'm sure that'll be dramatic watching him flop around while zombies bang on the door.
Then, once he's clean, he'll find a stash, and do it all over again...
Totally didn't see that coming.
Meanwhile, the "dad" in the family will try to exert command control over the family. Pretty sure that'll drive the teen daughter into rebellion fits, along with his own son who doesn't like him. The mother will likely resent that as well, as clearly she's command material from her job and he's just a teacher.
FotWD will be a cautionary tale of how most civillians got themselves killed.
