Laura, a bully, not a victim?
I recall that in much of the promotional material, Laura was described as a bully who then got bullied herself and that's why she killed herself. After seeing the movie, I think it's pretty clear that the writers originally had Laura as a bully (Ken, Blaire, and Mitch all mentioned that she acted rather mean; also in a text to Val, Laura apologizes for being mean but Val tells her to kill herself) but then changed it at the last second to make her more of a victim of bullying to give the film a more revenge-like taste.
Tbh, a bully who commits suicide because people ended up bullying her isn't a tragedy, it's more a poetic irony/justice; nobody is going to care if a bully kills herself, people would just say she got a taste of her own medicine. I wonder what kind of bullying shenanigans Laura got herself up to in the original version of the story? I suppose this could somewhat change how I feel about her ultimate suicide.
