#2 Dawn of the Dead (1978)
When you walk into a mall do you start checking to see where all the exits are? Do you think about how easy it would be to defend? How long you could hold them off and survive if necessary?

If you do, you're like me, and all the others who've had our minds warped by this classic. The brilliance of George Romero's zombie films is that he creates a world which we identify with and we immediately start thinking of what we would do in the nightmare that he presents us with.
 
He makes his horror personal.
 
We indentify with the heros and we recognize his living dead as the mass of humanity that surrounds us. In Dawn of the Dead he presents us with a gripping vision of a world gone to hell. Civilization has collapsed and we are on our own, people! Forget about crosses, holy water, and garlic. Forget about priests, wizards, or scientists. And there are not enough bullets in the world to shoot all the zombies that are lurking onjust the other side of the glass.
 
"When there is no more room in hell, the dead will walk the earth." What more needs to be said?
