Rottentomatoes.com, a pioneer in Internet movie reviews, features a “Tomatometer” that shows the percentage of positive reviews for a movie. Movies are labeled fresh or rotten. Those with more than 60 percent positive reviews are endowed with the title of “Certified Fresh.”
Metacritic.com calculates its “Metascore” for a film by averaging the rating given by critics, then assigns colors to signify the general rating—green for favorable, yellow for mixed, and red for unfavorable. The site also reviews TV shows, music, and games.
Moviereviewintelligence.com provides statistics for the number of positive reviews a film received, taking into account the size of its release and the types of publications in which the reviews ran. It also provides short excerpts from reviews by major critics.
