Reading the other reviews, telling people to keep their mouth shut if they didn't like this movie isn't okay. Just because this movie talked about an oh-so-important topic, doesn't mean it shouldn't be criticized either way. Yes, people put effort into this movie. But guess what? Other films that had lots of effort put into it gets criticized too. Sure, the movie was good to some people but to others, it could've been better.
The portrayal bullying wasn't so realistic. The main character isn't likable so you can't really feel bad for her when karma hits her. If anything, this movie was more unintentionally comedic than sad or thrilling. Therefore, I dislike this movie. And if you think otherwise, that's fine too. Don't get triggered over my opinion. Just get over it and move on.
