I think they should teach the children how to use at least some weapons. Then they wouldn't be so helpless. And though I agree that Sophia and her mother aren't very bright, I think it's interesting to see weak people in this too. I mean, weak not just when it comes to skills, but emotionally and mentally weaker than the others. Just frailer people, really.

That said, I think this show could do with a little improvement in the female character department. They're all pretty disappointing so far.

I like the random killing off people to a point. Luck certainly has its place in the situation they're in. But I'd like to see some managing because of skill too.
