The 21st Century's Most Acclaimed Films list serves as a companion to the They Shoot Pictures, Don't They? 1,000 Greatest Films of all time list which, - by its nature - tends to have very few films from the 21st century in it. The 21st Century's Most Acclaimed Films list attempts to highlight and honour this century's most critically revered films and act as a sort of 'resting bay' for many great films that are likely to be included in the 1,000 Greatest Films list sooner or later.

Well over a century has passed since the Lumière brothers frightened the life out of Parisians with The Arrival of a Train at a Station, and well over a million titles have since been recorded - if the Internet Movie Database is anything to go by.

Out of these million-plus movies, our team of experts has picked what we believe is the essential 1,000 - those that best sum up the dazzling achievement and variety of the movies.

Rotten Tomatoes - Best of year

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.
