On the review aggregator website Rotten Tomatoes, a film has a rating of 100% if each professional review recorded by the website is assessed as positive rather than negative. The percentage is based on the film's reviews aggregated by the website and assessed as positive or negative, and when all aggregated reviews are positive, the film has a 100% rating. Listed below are films with 100% ratings that have a critics' consensus or have been reviewed by at least twenty film critics. Many of these films, particularly those with a high number of positive reviews, have achieved wide critical acclaim and are often considered among the best films ever made. A number of these films also appear on the AFI's 100 Years...100 Movies lists, but there are many others and several entries with dozens of positive reviews, which are considered surprising to some experts. To date, Leave No Trace holds the site's record, with a rating of 100% and 248 positive reviews.
