I noticed that a lot of Giant Bomb users were complaining that games/movies/drinks were overrated as well as games being underrated either by reviews or the way the community or the world acts. 
 
I'd like to say that because you think something is amazing or you think something is terrible it's true.  When you say something is overrated it's because you don't like or get it.  I'm not saying that if you don't like something 100% of the time you don't get it.  Personal taste!  I know.  However when you preface your announcement on the overratedness on the subject by saying (Why does everyone like this bullshit cause I don't!!!)  You lose your credibility with a statement like this.  Just because you don't like/love something that doesn't mean there are millions or even hundreds of millions that don't. 
 
The same goes for the underrated activists.  When you find yourself defending poor controls/acting/story you have to notice why everyone doesn't like the game or know what you are saying.  I'm not talking about games that is considered good by everyone who experienced it but just never got that popular.  I'm talking about stuff that is popular but popular because of something really damaging or wrong with them that everyone sees but people ignore.
