On the film review aggregation website Rotten Tomatoes, films which are reviewed by at least five critics, and which all of these critics consider to be good films, have a 100% rating. Many of these films, particularly those with a high number of positive reviews, have achieved universal critical acclaim and are often considered some of the best. A number of the films also appear in 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.
