Metacritic is a website that aggregates reviews of music albums, games, movies, TV shows, DVDs, and formerly, books. For each product, a numerical score from each review is obtained and the total is averaged. It was created and founded by Jason Dietz, Marc Doyle, and Julie Doyle Roberts. An excerpt of each review is provided along with a hyperlink to the source. Three colour codes of Green, Yellow and Red summarize the critic's recommendation, giving an idea of the general appeal of the product among reviewers and, to a lesser extent, the public.

The site is somewhat similar to Rotten Tomatoes, but the scoring results sometimes differ very drastically, due to Metacritic's method of scoring that converts each review into a percentage that the site decides for itself, before taking a weighted average based on the critic's fame or stature, and listing different numbers of reviews. In addition to its Television ratings it also reviews music albums, video games, movies, and DVDs.


Metacritic's slogan is "Keeping score of Entertainment."
