Have you ever noticed in zombie movies that the walking dead can hear, see, and grunt no matter how rotten their bodies are? And they never seem to attract any flies. But they are very peaceful toward one another and never fight among themselves. In the meantime, if there is only two normal humans in a scene they are always fighting each other and ignoring the zombies. And if there are two groups of normal humans they are more interested in their own group than uniting peacefully into a larger group for better defense against the zombie horde.
The totally apostasy was predicted two thousands years ago in the Holy Bible. We are living in the Last Times now. Anything according the Holy Bible .
Our movie heroes are individuals and not groups even though they are always put in some kind of group. We all want to ne heroes and the media feeds us what it thinks we want. Like religions, it is all about the cash. Regards DL
