I think seeing this movie in theaters in the 60s would have a drastically different impression on me. Being in my 30s I obviously wasn't alive when this movie was released. I have seen so many other wonderously imaginative works of science fiction leading up to having seen this one a few years ago. It is difficult for me to imagine this movie, which still holds up today, as being one of my first introductions into the genre in a time where such visuals and concepts were not really a thing yet.
