Ask five different people what the greatest movie of all time is, and they'll all have different answers. That, or they'll all say Freddy Got Fingered.
Point is, assembling a list of cinema's finest treasures is an inherently subjective undertaking, and everyone's ranking is guaranteed to be skewed one way or another -- which is why one Reddit user decided to settle things once and for all by combining data from the most popular movie rating sites (IMDB, Rotten Tomatoes, Metacritic, and Letterboxd) into one master list for the ages.
According to the user (aptly named StopReadinMyUsername), the rankings required months of tweaking to ensure overlooked films received equal treatment with popular favorites, and points were carefully deducted based on how many people had voted on/seen each movie. After all, if there's one thing people on the Internet love doing, it's assigning ratings to things they've never tried/seen before.
