25 years would be a generation, just seems odd society's obsession with it lately.
I recently rewatched the Omen trilogy and only then realized that the movie was produced and written by Jews. Which really makes you wonder, you know, about Rabbinical Messianic prophecies and all. I guess the idea of the changeling is probably more prominent in Jewish culture than it is in the European, because of the ethnic dynamics.
Both in Omen III as well as Rosemary's Baby, which was written and produced by Jews as well, the psychology of the Antichrist's cults is totally reminiscent of how Jews would feel about Christianity. They aren't exactly edifying films, but well enough made and I think, very insightful.
Roman Polanski, who made Rosemary's Baby, is very much the incarnation of the vicious Jew stereotype, but he is actually so good as a film maker that you get a deep insight into his ideas about power (Macchiavellian) and religion (revolution) looking at his oeuvre.
The Coens, who I think are a lot more likable than Polanski, are likewise revealers of the Jewish psyche, although I think they view their origin a lot more critical than Polanksi. With the Coens, it always looks as if they would love to shed Judaism and become Scots-Irish founding stock Americans. Whenever they refer to Jewish culture, they do it while implicitly or explicitly naming the hypocrisies and contradictions.
Polanksi on the other hand thrives in being eternally persecuted by shadowy figures, as if he was victimized by his own evil impulses. In a way, all of his movies relate to that broader topic of persecution, disguise and compulsion.
Horror is a genre dealing with vague threats that capture the audience's imagination, so it's inherently attractive to Jews, who have the most paranoid obsession with vague threats.
Sorry for the big detour, but I think as the Western world became judaized, we all became subject to the fear of vague threats, culturally or demonic, that emanate from a godless lifestyle
