I tend to keep an eye out for They Shoot Pictures, Don't They’s annual update of their 21st century and all-time films lists.
TSPDT is a modest but fast-growing film resource dedicated to the art of motion picture filmmaking. More specifically, they’ve created an algorithm, assembling lists from all around the world to produce two highly-referenced lists: The 1,000 Greatest Films and The 21st Century's Most Acclaimed Films.
As far as I’m concerned this is the most comprehensive film list on the internet because there are no biases, just the data. Ask most critics/directors/historians and they would say that the list is reputable, especially the top 200.
Regardless, the long-awaited yearly update for 21st Century films has come and these are the results:
