/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.
Note: Two of the films were not on the IMDB, therefore not added. They will be added soon though
The 100+ Most Controversial Films of All-Time: Films always have the ability to anger us, divide us, shock us, disgust us, and more. Usually, films that inspire controversy, outright boycotting, picketing, banning, censorship, or protest have graphic sex, violence, homosexuality, religious, political or race-related themes and content. They usually push the envelope regarding what can be filmed and displayed on the screen, and are considered taboo, "immoral" or "obscene" due to language, drug use, violence and sensuality/nudity or other incendiary elements. Inevitably, controversy helps to publicize these films and fuel the box-office receipts.
Controversy-invoking films may be from almost any genre - documentaries, westerns, erotic-thrillers, dramas, horror, comedy, or animated, and more. Standards for what may be considered shocking, offensive or controversial have changed drastically over many decades. From the earliest silent films, to the gunfights in early 30s gangster films, to the mid-60s countercultural changes when the ratings were modified, to current day bloodbaths, violence in films has always stirred controversy. The voluntary ratings system of the Motion Picture Association of America can influence a film's public showing in a theatre -- an NC-17 rating or an unrated film may often close down a film's screening and lead to commercial failure.
