For example, back in the 50s the sci-fi movie "Invasion of the Body Snatchers" was a subtle warning about communism.
Classic movie. I watched it on TCM the other night and could really see the communist comparison. Like I said earlier, it’s the people who dress up like zombies and have a fixation for them that I find disturbing.
At this point the zombies have become a nuisance. It's other humans who are the real threat. And in a true SHTF situation, this is how it would be. Zombies are just the vehicle to put viewers in front of their TVs. An equally compelling story could get rid of the zombies altogether and have the scenario be a nuclear holocaust, ravaging pandemic or EMP attack.
The only story here is surviving in a world where all the comforts of modernity are gone, where the only thing that matters is staying alive, keeping your loved ones alive and where this is the only thing that matters to everyone you encounter.
And if you living means others have to die, if your children eating means other people's children have to starve, that's the cruel world.
