So I've noticed that there are a lot of streaming movies and TV shows that match a lot of these patterns:
IP is announced. Adaptation of extremely popular series with existing fanbase
IP is billed as "adult" with "mature themes"
Producer/Director goes on a podcast and compares IP to "Game of Thrones" a few weeks before release. Said comparison treats GoT as an ideal to aspire to instead of a cautionary tale.
Producer/Director also insults existing fanbase for some reason
IP is previewed to critics, gets amazing reviews
IP comes out, and gets high streaming numbers day one
Writing ends up being terrible
Plot ends up being surface level, with all the subtly of the original adaptation cut out. This somehow is true now matter how basic the source material may seem
Acting is terrible. There is at least one race swapped character, who they also butcher from a writing perspective
VFX is terrible, and expensive scenes are cut out
Costumes are terrible to the point where everything looks like shitty cosplay
There's a few violent scenes that are extremely gratuitous. VFX and writing are so bad that it's comical instead of jarring
There are a few random sex scenes thrown in. The sex scenes detract from the pacing of the story, and are blatantly thrown in so producers can brag about them
Sex scenes tend to focus on the female form. If men are involved, they all are hairless and look like boy band members
If it is a gay sex scene, it blatantly written by women and for women with an extremely limited knowledge of men as a whole
In a few days, the Internet erupts with needlessly vitriolic discourse about said IP.
A year post release, the show is essentially forgotten.
In that context it's no surprise younger people don't like sex scenes. It's basically a canary for a low quality show and extreme toxicity.
I didn't have anything specific in mind, but a lot of this matches up based on the one episode I watched. There weren't any sex scenes though.
The Air Nomad genocide happens within the first ten minutes, while Aang is on a walk or something. It's billed as this super metal moment that shows you this isn't for kids. However it looks so fucking cheap and is written so badly. I just sat there rolling my eyes.
To be fair, the online discourse part also didn't match up. The show got good but not great reviews. Avatar is a lot more popular that most adaptations, especially among millennial bloggers who do these reviews. While there were the usual 9/10s, there were also a ton of reviews written by people who grew up watching the show that were just like "yeah this is disappointing in every way. I guess it's okay if you didn't watch the original show, idk you do you 5/10". Because of the diversity of the original IP, there was no culture war BS either.
