I think the mistake the writers have made wasn't showing the family drama, it was creating unlikeable characters.
People would be okay with the family drama if they could actually get behind and support the characters, but after the first episode, I found the only enjoyable main character is Travis, simply because he's more honest and open about what's going on, and he's an awesome teacher, and very supportive character. The mother's denial and blindness throughout the entire episode was plain annoying.
The sister might be okay, but so far she hasn't done anything to really make me want to care for her, and while Frank Dillane might get nominated to receive awards for his portrayal of a drug addict after that first episode, the untrustworthy betrayal he demonstrates during the episode makes it very hard to care about his character's survival in future episodes to come. I guess I just have no patience for weak characters like him.
I don't think there has been a series in the history that has made me to root for the characters at the beginning. They could have gone down scientist PoV and show viewers when the science community got a hint about upcoming devastation. Equally they could had written something similar to what happened at the beginning of last years Ebola outbreak, and shown that there were "interested" people doing a "data-mining operation" that "they'd briefed on WHO" earlier. Instead of that we got a pimple faced youth with a small fruit knife in his pocket mumbling something that "it has crosses five state-lines." That, if nothing else, is a mark of tinfoil stuff seeping back into the mainstream culture.
In fact, I was more interested on seeing how people were totally clueless about the upraise. And like I said, it's nice to hear helicopters droning in many scenes, sirens veiling in the distance, not talking about hearing people chatting and seeing them using mobile phones. All those things are pretty much gone in the original series, and if they appear, they're always plot devices rather than just everyday background items.
However, interestingly I was rooting for the drug kid and cheered when he rammed the truck on a zombified drug dealer purposely. He meant to kill even if it didn't happen. Equally he and his "parents" failed to commit one significant brain injury, so it's back in the days, when people know nothing about the undead.
What the journalists were really expecting? I don't know, but I'm interested to see how the scenario evolves and how soon the "family" finds them escaping the city. Other things I'm waiting to see is government's response, FEMA camps, Quarantine Zones, panic and resulting chaos in ordinary citizens, looting and mass hysteria AND an explosion in zombie numbers.
What would be really interesting to see is Patient Zero and originating location.
