I'm fine with plenty of sex on TV. Game of Thrones seems to have broken the barrier in people's mind for gratuitous sex and nudity in the mainstream and streaming services have capitalised on not having the same restrictions as terrestrial TV. Sex is an important part of human existence and it's fine to have it feature heavily in our media. The same rules apply as for anything else in story writing.... It must make a point, fit into a narrative and be done well.
A few media review sources have had good video essays and articles about the fact that:
- The most recent generations are really objecting to sex in their media. So tastes are changing. Objectively there is less and less sex in our movies and TV shows.
- It is very important to show normal sex as part of a normal story. If this is not maintained, then the only way to see any depiction of sex will be porn, and porn is so warped and far from reality that it really should not be our main depiction of sex.
If stories are going to be written, then there will inevitably be bad stories and poor implementation too, and we just have to put up with that. I haven't seen the media you mention.... Maybe it was bad, or maybe it wasn't for you. Either one is fine. If you want to find good shows, you risk watching some bad ones.
