If there is no fate and our interactions depend on such a complex system of chance encounters, what potentially important connections do we fail to make? What life changing relationships or passionate and lasting love affairs are lost to chance?
The main jokes in this film are about big things, love and life and zombies - we all get that.
We suddenly saw how people reacted in the event of massive social upheaval, and the way that the little problems in your life don't go away. You don't stop being frightened of spiders just because the world's blown up.
