These are strictly the opinions of a 43 year-old with a master's degree in cinema and not based on anyone else's. How many have you seen? Films are listed in alphabetical order (with some inconsistencies due to alternative titles). Film ratings list at https://scottandrewhutchins.wordpress.com/film-ratings/ Criteria include originality as well as skillfulness in directing, writing, cinematography, editing, composition, and acting. This list is not necessarily my favorite films to watch, although there is significant overlap. I hope this list inspires people to seek them out. Films I've seen since that I want on this list: Far From Vietnam, Experimenter, Falstaff (2001), Little Women (2001), The Love Witch, Secret Beyond the Door..., Wonderstruck.
There's one film here that I have not seen, and that is Intermezzo (1936). I included Intermezzo (1939), an American remake of the 1936 film, both starring Ingrid Bergman, and the site changed it on me. I have asked them to fix it.
