You are right it is culture. The sexuality in WoP changes tone and feeling of the material.
No language per se—my example of language was a guy in the locker room at work. Depictions of sexual intimacy are generally what I am complaining about. Allana and her 2 warders rolling around in bed (early S2 episode) is both a ridiculous portrayal of sex and used more like a middle school tee hee hee moment. Not anything to do with the plot, I guess it is character developmemt(?). Such things were not described in the WoT in the slightest—the closest being Avienda and Rand in Seanchan land.
Many of the characters depicted in the show really are not who Jordan made his characters to be. No relationship between Rand and his 3 loves, Min prolly doesn’t swing that way(?). We have girls hopping on top girls with no developing of relationships with Elayne and Avienda—it is just titillating girl on girl action IMO. Nynaeve is not her motherly, know it all, school marm prude from the books. I like this Nynaeve, but she is a different person. Galad is not himself either, I would argue neither is Gawyn. Moiraine debating if she is gonna hook up with a Wise One she doesn’t know. Sex with randos at a drop of a hat.
I like that they showed the sweat tent, and how they kept the nudity to a minimum.
