Oh it’s weird and kinda campy – to be sure. It definitely reflects the late 60s drug and sex ethos – but then again, considering the nudity in Classical art, (not to mention the homosexuality, pedophilia, and slavery) – one might judge the film as rather tame. Nonetheless, I think it’s highly underrated. I could see how it’s flashiness and novelty might overshadow the deeper qualities of it. It’s one of the few stories that believably speculates on the idea of immortality, and the creation of a Eutopia (including class-consciousness, human indifference to the suffering of others, and biological determinism, which have often been taboo subjects, despite their immense influence in society)… and how that Eutopia could stagnate and decline into a Dystopia.
