I've been thinking about what zombies represent for us and why there seems to be a growing zombie craze these past few years.
It's said, by whom I do not recall, that the Japanese film craze for giant monsters, such a Godzilla and Gamera, represented for them their fear of the wide spread destruction they suffered at the end of the Pacific War. Also, their fear of the long term effects of radiation.
In the 50's, Amercian sci-fi movies that dealt with world conquest (War of the Worlds for one) might be considered a fictionalization of the fear we had at the outset of the Cold War and the fear of Communism. Later, in the 70's, films like Logan's Run, Soilent Green, Planet of the Apes could be seen as dealing with suspiciousness of our own government or perhaps the fear of its trend toward collectivism or corruption in general.
Vampires seem highly romanticized in today's culture. Maybe they represent wishes more than fears--the wish for unending life, thus unending love.
So, what does the zombie craze tell us about ourselves?
