The scientist type explains that the zombies want to return to the place where they were the happiest. I thought that was a pretty funny comment on shopping mall culture.
Is a grocery store the best place to spend eternity?
Back in the 70s, 80s, something always struck me when I saw one of these gargantuan shopping malls:
When we dig up the ancient past, we find temples to the gods, and to the ideals that they represented to the people. When they dig up late 20th-early 21st century America, except for a few pretty monuments and churches, they’ll find enormous temples devoted to Consumerism...
(I don’t think many ancient people built such permanent and imposing structures specifically for mere buying and selling...their minds seem to have been elsewhere.)
