Propaganda is everywhere. Especially in super hero movies where they can remove ambiguity by writing actions that make bad guys unambiguously bad. They justify the heroes with these clear cut good and evil situations. Like in Batman when he kidnaps the guy from Hong Kong because Joker is making his points using grand displays that kill a bunch of people. Or in 24 when they carefully craft a situation where torture looks sensible (and maybe even pays off? It's been a long time, I can't remember if they show torture as a "justifiable" but ultimately useless act, or if they portray torture as an effective way of obtaining information when the tortured knows they only have to hold out for 24 hours).

The Boys does a better job with this by making the idea of heroes saving the day itself the villain and highlighting the corruption that would likely go along with such power and reputation.
