introduce a dual rating system for critcs & fans to provide more accurate scores

Creating our proprietary Metascores is a complicated process. We carefully curate a large group of the world’s most respected critics, assign scores to their reviews, and apply a weighted average to summarize the range of their opinions. The result is a single number that captures the essence of critical opinion in one Metascore. Each movie, game, television show and album featured on Metacritic gets a Metascore when we've collected at least four critics' reviews.
