I agree with the general sentiments here as well.
The only take-away that I thought was interesting was the fact that the Boyfriend/Step-dad character (sorry, I don't remember anyone's names) showed some serious balls by going into that church by himself. Yeah, part of it was probably just "blind courage" but minimally, it could have been a drug addict on a really bad trip, violently lashing out - either way (walker or dude high on bath salts) - he still was willing to put himself into harms way for the sake of his family.
Kind of gives insight that he's a resourceful, survivor type, so that way when it comes to the end of the six weeks and he's still alive we're not left thinking "how the hell did the high school teacher survive?!?!"
And for anyone not liking the drug-addict son of the female lead - I'm pretty sure I caught a shot of him with a bite on his foot in the coming attractions, so his days are probably numbered. Would make sense, even if they wanted the show to be about a "family unit" and how they survive a zombie apocalypse, that unit could simply be the two leads, the female lead's daughter and the male lead's son from his previous marriage.
Here's a perfect example of what Scott Gimple was talking about us knowing more than the characters. Travis went to the old church just thinking his junkie soon-to-be-stepson may have seen something, but his account is unreliable because he's an addict. He didn't expect more than a bunch of strung out junkies zoning out after their fixes. We know there was at least one zombie in their earlier, because we know what's coming. They don't....and their primary source to the "there's something odd going on here" plotline is a junkie.
Now, when they see Calvin...that's the game changer.
