In Game of Thrones and Western media in general, incest is usually treated rather differently though, being a shorthand to show someone being completely morally decrepit
That's true. I just meant the absolutely braindead season finale for the show was absolutely hilarious for me. Like watching that show fall apart was the most entertaining it had been in years.
What gets me is how often sibling incest is portrayed as this sweet, star-crossed romance thing in Japanese media
Honestly eh. So incest isn't big in Japan. Which just leads me to think that this falls under the general misogyny of that society. And boy oh boy is a freak show. I mean considering whose been running that country and at whose behest. It probably fits. Plus it's like at the end stage of capitalism (as in a society that has successfully implemented capitalism as well as possible) and what you find there is a soulless abyss. Japan more than the rest of the world (although under capitalism we're all there to some degree) is a direction less society and profit just doesn't cut it. On the flip side they produce some seriously good but seriously depressing media. Stuff like land of the lustrous or technolyze.
Also the way your wrote this post up was really funny. Like it really captures the feeling of watching a piece of media fall apart. This was me when I read this manga called usagi drop. I literally couldn't believe it. I was genuinely shocked. This was well before I realized how ridiculous Japanese media can get.
