Wikipedia:Review aggregators

Review aggregators are websites that collect film reviews and reflect overviews of critical reception by providing a score for a film based on the reviews. Some review aggregation websites, such as Rotten Tomatoes and Metacritic, are considered reliable sources, but information from them should be used in proper context and have some limitations. Each website follows its own scoring process, so they are typically paired in articles to offset each other. Review aggregators are not arbiters of critical consensus; sections about critical reception should also benefit from other reliable sources, such as books and periodicals reporting in retrospect how a film was received by critics.
