Today there are many similarities between modern "fandom" cults, centering around movies, video games, TV, comic books, etc, and their similarities with pagan religious, such as the gods worshiped by ancient Greece.
It seems that people who lack purpose in life attempt to instead live 'vicariously' through their favorite TV, movie, video game characters, celebrities, etc, and develop rabid 'cult followings' around them, to the point that they're no longer just a pasttime, but a way of life.
In a way this bears resemblance to the nature of ancient pagan religions, in which there were many 'gods' but none necessarily requiring exclusivity, and the 'gods' were merely akin to 'powerful mortals' with the same vices of men (as distinct from religions such as Buddhism, which acknowledge one universal standard of all morality and truth, and did not acknowledge mythical pantheons).
I find modern obsessive fandom an example of human's lesser nature repeating itself, with the pagan deities once worshiped by masses merely surrogated with quasi-"worship" of fictional characters on TV or other media.
