Its explanation is simple and I saw it coming decades ago.
Movies (their cretors) became more interested in social messages as opposed to entertainment, it’s progressed to the point with leftists in charge, liked Kennedy with Lucas Films, only care about the indoctrination.
This South Park clip is perfect—-and I have to add many people, shockingly even some of FR still cling to the idea movies are never biased politically:
I lost about 70% interest in modern movies the moment I saw a gun control poster displayed in, I believe, “Lethal Weapon 2”.
