The Greatest Films can't be measured scientifically because greatness is extremely subjective. The artistic greatness of films (and other works of art) can never be rated or quantified, although critics, reviewers, and fans still make ten best lists, hundred best lists, all-time greatest lists, favorites lists, awards lists, and generate results of polls. Over a long period of time, it has been found that the English-language films found here in this selection of 100 Greatest Films repeatedly appear on all-time best film lists and are often noted in the collective responses of film viewers.
