Somebody brings this up every year, and the answer is always the same. The Oscars are not about popularity. If you want to know what the most popular films are, just look at the list of the box-office winners for last year:
The Oscars are also not about the critical favorites, which you can use this list to discover:
They are always somewhere between these two extremes. They are always very middle-brow. Not low-brow like the box-office winners. Not high-brow like the critical favorites. So box-office winners like Guardians of the Galaxy, The LEGO Movie, Transformers: Age of Extinction, The Hobbit: The Battle of the Five Armies, Maleficent, or Big Hero 6 might get some nominations for the various technical awards or for the animation award (which the Academy thinks of as just kid’s stuff) but seldom anything else. It’s not some of the critical favorites either. It’s not things like Under the Skin, Ida, Only Lovers Left Alive, Force Majeure, Mr. Turner, Two Days, One Night, Goodbye to Language, or The Immigrant. Those might get foreign language film nominations (which the Academy thinks of as a consolation prize to throw at the rest of the world), but otherwise they are considered too foreign, too weird, or too boring.
The Academy wants films that are in English, set in the U.S., with stars recognizable to them, with directors recognizable to them, not about arty things, without kinky sex, and about subjects that are familiar to them like American wars within memory or American political struggles within memory. They are O.K. with films that make offhand reference to things that audiences might understand like the stars of superhero films getting replaced or famous scientists who’ve appeared on Star Trek.
This is an unusual year in that the top three critical favorites are also on the Best Picture ballot. They have just enough audience-friendly elements that they can satisfy both critics and most American audiences. They have no explosions or ear-piercingly loud music and have little special effects, so the Academy can convince themselves that they aren’t nominating low-brow films.
And the Oscars are going to stay middle-brow, so don’t expect them to be otherwise.
