That's giving the movie industry more credit than they give themselves with the Oscars.
It's obvious advice but so many people had absent parenting and ended up as failures and need to be told the absolute basics. If they get this advice from social media or corporate media, they are being led in the wrong direction.
Obviously some parents are undeniably negligent, but let's take care not to blame them as a homogenous cohort.
My point is that yes, there are a lot of people out there searching for life advice and self improvement. They suck it up from books, movies, social media, the news. Some of that advice is absolute crap and some of it is beneficial.
There are absolutely people who will see personalities in movies and try to take something from that. In fact I’d say none of us are immune from doing it.
My sister has 3 kids under 10. Every day they watch at least 3 movies, some of them atleast presentable as childlike learning, the others are just "whatever Netflix puts on"
I would argue the most damage has come from the near complete and utter erosion of social communities. As the saying goes, "It takes a village [community] to raise a child." I can't name a role model in my community. In fact, I have no community that I can access without the Internet.
We went from "Survive together; thrive together" to "every man for himself" way too rapidly.
Children learn implicitly from the behaviours they see - mostly mimicking others.
Adults do the same thing. However most adults think they make conscious/rational choices, and they think they are not driven by subconscious behaviours.
I am not saying we learn to be killers by watching murder mysteries. I am saying we subconsciously learn some behaviours from the media we watch.
