Metacritic is a website that collates reviews of music albums, games, movies, TV shows and DVDs. 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 colour codes of Green, Yellow and Red summarize the critics recommendation. This gives an idea of the general appeal of the product among reviewers and, to a lesser extent, the public.
