For the social media/performative side of the issue: I think that we are seeing the effects of instant online judgement at any moment (who wouldn't want to play it safe), the ability to monetise yourself and sell yourself out in less than a minute from anywhere in the world, and the ability to follow the norm to a ridiculous level with the invention of day in the life and lifestyle videos.
As for movies: I think that since movies introduction into the mainstream they have always played an important role in guiding how people see the world, usually for the better. They normalise scientific concepts, abstract ways of looking at the world, introduce potentially new emotions to the average person, ways of conversing, and used to promote the idea of human ideals and beauty. Generally, when movies have been more genuinely creative and kind to the idea of human greatness society has tended to be happier and more creative. I've seen lots of directors use this for good, and I'm yet to see explicitly malicious use of western cinema (excl propaganda). I don't think it's bad that we're all in different worlds, people have been at different levels of awareness and connection to reality for as long as we've been around, but well executed movies change us more than many of us admit.
As for anime, it's really interesting how animated pictures do something different to me, they almost feel more cerebral, like it's how I really see the world in my imagination.
