Alan Moore and the rise of edginess in comics are perfect examples of liberal deconstructionism ruining a genre/medium.
Leftist hate reality/nature so when they gain control of fiction they subvert the main themes that made the genre successful in the first place. Superheros go from being about altruism and making sacrifices to help others to be a scowling hatefilled thug. Alterantive music went from being about fun and having a good time to wanting to kill yourself and be an outcast. Fantasy goes from being about comadre and different cultures uniting for a common goal to polical back-stabbing.
And once the subversion of these genres becomes a cultural opus they fall apart. Superheros comics in the mid-90s collapsed and survives off of cartoons and movies. After a decade of grunge/industrial/nu-metal/emo Rock and roll was dethroned by rap. I suspect the fantasy shows following game of thrones will downplay the fantasy elements in favor of banal polical intrigue that will amount to the West wing with elves. They unlike the former will likely drop this trope once it starts to loose money because movies and tv shows are a bigger financial investment.
Before something is subverted or deconstructed inquiry should be done about whether this is smart. A pillar holds up a house.
