I just finished watching the last episode, and very much enjoyed the series as a whole.
But I am more and more having a problem with one of the core ideas of the premise. Namely that the group of functioning retards that are our heroes could survive as long as they while any governmental forces or other organized forces(so far as we know) have been wiped out.
Due to the families in the show being largely intact, it seems a reasonable assumption to assume that whatever causes "zombie-ism" is not air-born. You get scratched or bit by a walker and you turn into one, simple enough.
So how the heck did the world fall apart from that?
I served in the United States Army in Iraq, I had bad guys shoot at me, try to blow me up and mortar me all day long. There is no way a bunch of brainless shambling walkers are going to destroy any country with a modern military. It just ain't gonna happen.
Let's just use Atlanta as an example. Everyone in it is infected. Several million walkers. Our engineers could throw a ring of hesco barriers around the city in a day or two, topped with concertina wire with a scoped rifleman posted every quarter mile or so. Every few miles we set up a kill zone. One Bradley fighting vehicle equipped with speakers playing music to suck in the walkers. Our standard loadout in a Bradley(in the Armored Cav anyways) was 1500 rounds for the 25mm, and 2200 7.62mm for the co-ax. With the optics on the Brad every shot can be a dead on kill shot. And we can sit in place for three days or so running on just our internal fuel.
My scout platoon of six Brads and thirty soldiers could thus kill 22,200 walkers using just our vehicle combat loads. Plus another 6,300 from our personal rifle loads. All done while totally impervious to attack.
Maybe Hollywood just doesn't understand what sort of firepower the military has at their disposal, but it is plot holes like that, that make watching the show more and more annoying to me.
