Why a game with a lower review score could be better

I think there is a place for a rating system, but it has to be cleared up and standardised. the criteria keeps changing all the time for every game for every platform.
Yes there will always be a difference in opinion but if every reviewer uses a standardised system of rating, the only difference in scores will be the difference in personal opinion and thats where metacritic would be useful, to see which opinions are grouped and which are isolated.

I'd like to see a Rotten Tomatoes for video games, which mainly takes into account whether or not a review is positive and negative. They also specify top reviewers, which is nice.
