I actually view 2012-2020 as peak “PSA messaging” era more, which a lot of people would probably coincide with the liberal optimism from Obama and course-correcting anxiety of Trump term 1. I think since covid Hollywood has “toned it down”, because the US has by and large moved on from that social phenomenon.
I’ve been in Los Angeles for over a decade, and I disagree with the premise that Hollywood has some overarching plan to shape how we think— more people watch TikToks than movies and network TV. I view Hollywood, and the creators/writers/producers of films themselves, moreso holding up a mirror reflecting the current circumstances we’re in rather than manufacturing it out of nowhere.
