As a long time superhero fan it's been interesting to follow the dicousre about "the boys" and how it's gotten "worse" over the seasons.
Again, I don't like "the Boys" simply because I'm over grimdark deconstructions of superheroes. As the seasons have progressed, the Boys fandom has complained about many things but I was surprised to find they are complaining about everything becoming so dark and raunchy. Like I thought that was part of the charm, Y'know? seeing shitty people abuse power without regard.
So yeah I kinda feel like saying "See I was vindicated in believing shows that revel in cynicsm end up disappointing their fanbases". But of course the problem of shows like "the Boys" and the way the GOT novels are stuck in development is more complicated.
The nuanced analysis I have is that with so much grittiness and cynicism permeating the story, that chokes out the narrative motion. You can only play the "greatest hits" of grim and dark themes like "might makes right" and "breaking away from the status quo means destruction" before the audience gets bored. Eventually, to break the status quo you'd have to add idealism, nobility, altruism or the like in some capacity.
The commentary on "why people like grimdark" that I've seen is that people like it precisely because good grimdark acknowledges how difficult it is to have noble virtues and ideals and how they are still necessary in a world ruled by self-interest and suspicion. In this way this little windows into goodness punch harder, and it's never free; it comes with dire consequences.
But apparently that's not what has been happening in The boys and the GOT books. In the quest for pungent social commentary and "realism" the authors of these works have painted themselves into a corner where the protagonists gaining ground would feel unearned because the odds are so big and the characters are just not the type to power through the odds with belief alone.
So... how are the finales going to be? will the fandoms be satisfied? Personally I think that no; the story will have a bittersweet ending that the fans won't like because it's meant to reflect the story. Or it will have a resolving ending that they won't like as well because it'll feel unearned. Either way it'll be interesting to see from the sidelines.
