The highest-rated documentary movies ranked by real audience approval — the percentage of everyday viewers who actually enjoyed the film.

What are the best documentary movies of all time? ThumbScore answers that question using real audience data — not critic reviews or algorithmic recommendations. Our ThumbScore rating shows the percentage of everyday Google users who gave a movie a thumbs up, making it a direct measure of audience enjoyment. This page ranks documentary films by that score, so you can find the most compelling documentaries that real people actually loved.
Unlike traditional movie ranking sites that rely on critic consensus, ThumbScore reflects the voice of everyday moviegoers. A 92% ThumbScore on a documentary means 92 out of 100 viewers enjoyed the film. We also show the Critics Score (an average of Rotten Tomatoes and Metacritic) so you can compare audience and critic opinions on the best documentaries. Use the decade filters and search above to find your next great documentary watch.
