Same zombie formula, victims victimize themselves

All zombie movies, good, bad, and fair, use much of the same formula.
Human soon-to-be-victims-to-be-turned-into-zombies make themselves easy targets for zombies because of their own weaknesses.

1) Inability to accept that a dead loved one is no longer a human but a mindless apex predator that must be put down immediately but they hesitate or refuse and allow an zombie loved one bite them.

2) Allow inchoate panic and fear to drain all strength and ability to resist, just standing there screaming and flailing their arms weakly about.

3) In every zombie movie it takes a long time to discover that zombies must be shot in the head.

4) Instead of banding together, in every zombie movie, survivors have to fight among themselves, leaving themselves more vulnerable to being surprised and overwhelmed. Survivors allow typical human flaws of greed, anger, envy, and selfishness to undermine their survival.

5) Inability or refusal to learn critical lessons about dealing with or fighting off the walking dead.

P.S. We all love zombie flicks so much because it's a safe horror, meaning, zombies can never exist for real. Just as the laws of physics cannot be broken for example, reaching and exceeding the speed of light, the laws of biology cannot be broken. No beating heart to pump oxygen-giving blood, and brain death after ten minutes of oxygen deprivation all mean no such thing as zombies, ever. Zombies horror fantasies exist because humans have had to confront our own mortality and death, sometimes unnatural and violent, for countless millenia. The fear of not resting in peace and the violation of our bodies after death is what gave rise to prehistoric fears of the walking dead.
