well. metacritic is a site that combines all the ratings of everyother site, be that site an official gaming site OR a random blog a normal person made.
sometimes those random blogs are way too biased and just want to make the games look bad, sometimes those blogs are too much of a fanboy of the game that they give it a perfect score
ive talking here from experience i know people (not going to mention their site name) and they are way too biased toward Call of Duty being the best shooter ever , that they gave KZ2 a 7/10 score and gave Halo 3 a 8.5/10 while all CoD games got perfect scores
have you guys ever heard of these sites? seriously
