Episode 1: - thumbs up. I like that it's in L.A. - just because I recognize the landscape. The Tom Cruise movie "Collateral" captured present-day Los Angeles better than any movie I've ever seen, but this was pretty good.
One piece of Walker-science I hope gets answered is why the kids at the school stopped showing up as the Zomb-pocalypse picks up speed. My understanding is that every human is essentially a carrier for the Zombie-virus, but it doesn't kill you on its own. You die however you die, and it turns you, then you come back. So are the kids actually getting sick with something, or is that a cover for something else? I don't see adults getting sick from anything.
