Because it's inherently ridiculous. Mind control? Possession? Sure, there's subliminal advertising (which is typically prohibited) and there's the Holy Spirit, but this is an exaggerated extreme with no credible basis in reality.
You can take any two or more things and find a connection between them if you're specifically looking for one. Are you familiar with "
Dark Side of the Rainbow"? It's the practice of simultaneously playing 'The Wizard of Oz' and Pink Floyd's 'Dark Side of the Moon' together because there are moments where the movie syncs up with the music and lyrics. While that is true, there are far more instances where there's no sync whatsoever. It's just coincidence...likely made up by people who've done
way too many drugs. Likewise, I once saw a feature-length "documentary" uploaded to YouTube where some guy analyzed supposed symbolism in every scene of Stanley Kubrick's 'The Shining' to claim that the movie was Kubrick's confession to helping fake the Apollo moon landing. It has almost 2 million views, but that doesn't lend it any validity; it's been criticized and contradicted by pretty much everyone, including people who worked on the actual film.
The eyes, along with the face as a whole, are a focal point of the human body. We show faces on everything, and typically the eyes, mouth, hair, etc. are emphasized for stylistic purposes. We see eyes because we see faces, and we see faces because nobody wants to see toes or bellybuttons or armpits on their cereal boxes or movie posters.
Movies about the apocalypse are just as prevalent as films about natural disasters or alien invasions or giant robots or outer space battles because big-budget special effects spectacles make a lot of money. Take a look at the highest-grossing films of all time and you'll notice that many of them are packed with special effects. And of course apocalyptic movies are going to be about trying to "stop it from happening"...who wants to go see a movie where literally everyone dies at the end?
That selection of quotes is nonsensical; few of them have any actual relevance to one another, the use of words like "spirit" are in wildly different contexts and many of the people quoted aren't even involved in Hollywood filmmaking or the American music industry. Some of those quotes merely refer to the practice of method acting, where an actor attempts to psychologically connect with their character for a more authentic performance. Some of those quotes are just musicians explaining the sensation of their love of performing or the weird disconnect of performing before thousands of people (something I've actually experienced, and yes, it's bizarre). Nobody is outright saying "I get possessed by demons when I do my craft".
Pedophilia is an issue in Hollywood, sure, but so is racism and sexism. That's a reflection of the ills of our society as a whole rather than an indication of a secret Illuminati cabal. The "dark stuff" in Hollywood is no different than what happens in any other facet of our civilization, as far as wealthy perverts are concerned.
It's clear that I won't change your mind by myself, and that's fine because that's not what I'm trying to do. I think all this stuff is ridiculous, sure, but it's your own freedom to pursue interest in what you want. The only thing I can suggest - nay,
stress - is to examine all sides of the issues from all viewpoints rather than taking any one person's biased word for it and coming to your own educated conclusion. The internet heavily blurs the lines between fact and fiction and evidence and opinion, so be careful about anything you read or hear.
