Metacritic is a website that collates reviews of music albums, games, movies, TV shows, DVDs, an books. For each product, a numerical score from each review is obtained and the total is averaged. An excerpt of each review is provided along with a hyperlink to the source. Three color codes of Green, Yellow and Red summarize the critic's recommendation. This gives an idea of the general appeal of the product among reviewers and, to a lesser extent, the public. (For examples of other such sites, see Category:Video game review aggregators.)
