/u/StopReadinMyUsername on reddit combined the average ratings (Critic's & Users) from IMDb, Rotten Tomatoes, Metacritic and Letterboxd, and then weighted and tweaked the results with general film data from iCheckMovies and IMDb to reveal the 1001 Greatest Movies of All Time.
This is a list of every movie that has made an appearance on the Top 250 list since the beginning of the site in 1996 through 2023. I will maintain a changelog below for when new movies are added to list.

My list of all-time classics, genre-definers, and can't-miss films & TV series. Whenever anybody asks me, "What should I watch next?" this list is my response.
While not everything here rates a 10/10 (though nothing falls below a 7/10 by my reckoning), each entry is at least an important cultural touchstone or an ambitious artistic achievement that is worthy of your valuable time.
I started off by gathering ratings from IMDB (User/Critic Average), Rotten Tomatoes (Tomatometer, Critic Average, Audience Score, User Average), Metacritic (Critic Average, User Average) and Letterboxd (User Average). I was then able to determine a rating (out of 10) for each individual rating and therefore come up with an average rating for each site. Each site’s average rating was then weighted fairly so that no site’s ratings were favored above the rest.
The next step was to make sure that each film was treated fairly. Other top movie list’s like IMDb’s Top 1000 removes films that have under a certain viewing number (25,000 I think), but rather than ruling out films that may have been overlooked by the general audience (especially older films), I opted to alter these films score by carefully deducting points depending on how many people have seen it, and therefore voted on it. I also thought it was needed to make sure that recent films (released within the past 36 months) were also not favored, as it usually takes 3 years for the average rating to settle down. So I also added a deduction to these films that fell under this rule.
