Lindsey Ellis had an interesting video a few years back reexamining the hatred for Twilight and Stephanie Myer that delved into this.

Yes, the vitriol Twilight gets is not appropriate for how just kind of regular the books/movies are. People are very uncomfortable around teen girls exploring desire, especially if it's the "wrong" way. It's weird once you start to notice it.

Ooo I dunno. That book glorifies an extremely abusive relationship, and also is appallingly badly written. I hate it a lot but really like a lot of romance and YA.
