I found over 18 lists of “Best Documentary Films of All Time” on the Internet and combined them into one meta-list. Here are the results, organized chronologically. This list includes every documentary on at least three of the lists. I’ve included the number of lists that the film is on. If I’ve seen the documentary, I’ve also included my 1-10 rating, For a version of this list organized by rank (i.e., with the films on the most lists at the top), go here.
