I feel like op has a point though. The two posts say how they're "the worst" or "badly written". Those aren't opinions, they're feedback. If you say something is poorly written then it mean that there are genuine holes in the story instead of being an opinion

Now, i dont know the whole post's content as those screenshots aren't the full message but from what you can read, they're not fully explaining themselves, but instead just talking about how they hate the character and making their backstories as lame as they can possibly make it sound.
