Formerly part of this list. Extracted because of the ratio of docs in the main list and also the disproportionate amount of reviews they have compared to fiction films and updated every Sunday through 2017.
Extracted from here. These lists follow the same eligibility rules for my 'official' Letterboxd top 50s since 2016. Unlike how Metacritic's year rankings use U.S. releases, I go by first national release by any country, excluding only festival releases.
See Metacritic tag for other top lists.
