Letterboxd's Top 250 movies, based on the average weighted rating of all Letterboxd users. I removed all stand-up specials, concert films, documentaries, shorts, 'collection listings' and other 'rarities', so only feature length narrative movies are listed here.
To avoid any discussions about documentary or not, Letterboxd genre classifications are used to remove them.
My friend Jack Moulton made a list of Letterboxd Top 100 documentaries though, go check it out!
