I happened to see a clip from the old Godzilla series yesterday ("Mothra vs. Godzilla"). Originally, the film was released in 1964, when I was 2. I remember seeing the film in a theatre just before I entered the primary school. It must have been one of the re-runs.
Godzilla appeared to be something of primordial brutality when I watched it as a kid. The way the monster was depicted, it was clear that there was no way of establishing a means of communication with it. Of course, as the Godzilla theme developed over many films, the monster "evolved" to display some comical features. It even played baseball in a film co-featuring some sea monsters. In the beginning, however, Godzilla was portrayed as a leviathan moving about on its own instincts, where nothing is negotiable. And it is in this primitive context that Godzilla impressed the young child.
As many point out, Godzilla has something to do with the collective trauma of the Japanese people in the post-war era, especially as regards the atomic weapons.
It is interesting to consider, even as I was not aware of the detailed history of my mother land in the years preceding my birth, I was somehow unconsciously affected by the implications, in the reception of the way Godzilla was portrayed when it destroyed the landscapes of contemporary Japan. Symbols are very powerful, and can reach the very bottom of your soul without knowing it.
