WD has one problem. It makes mankind totally helpless. Unlike World War Z where the zombies are very fast and strong, the zombies in WD are slow lumbering creatures that can easily be killed by fast mobile human killer teams. All mankind needs is one good stronghold that can protect a large organized population and field a small mobile killer team that will first clear the area of zombies and go from there. Good cold winter weather and the zombies are going to become less mobile as their body fluids freeze. Killing them would be even more easy for human forces. If SHTF the worst role to assume is refugee. You are limited by what you can carry and at the mercy of local forces. Since the characters lost their prison stronghold, they have become refugees.
More people in WD get killed by people than zombies. The show doesn’t make mankind helpless, it makes them dangerous. Some people want to rebuild, but they aren’t all good people and they don’t all have good ideas for rebuilding. And others just see it as a chance to have fun with no rules. In the books they’ve done an entire year without the zombies killing anybody, though many people died. The zombies are really just a background threat, like bad weather, only really a problem if you get caught unaware or wind up in the bath of a horde. People though, they’re always a problem.
1. Pure theory that's never been proven.........kinda like global warming.
2. They're where, Georgia? North Carolina? Walkers aren't going to freeze down there nor will they require snowshoes in order to walk thru snow.......
3. Due to the total breakdown of society and all its amenities such as radios, cell phones and definitely TV, we don't know how the northern states are surviving this apocalypse......
Rumor has it, the producers of TWD are considering a spin off of this popular series and it will be called "The Frozen Dead - North to Alaska" and they will appropriately try to resurrect both John Wayne and Stewart Grainger in title roles........We'll just have to see how that pans out.
