Misinterpreted ? Maybe, maybe not.
The movie itself doesn't need to speak to anyone on a deeper level. It's (imho obviously) not in the same league as a motion picture as say, Winter Soldier. It's cast, creative team and timing are, I would suggest, it's true usp. That's the driver for it's cultural impact, not the quality of the movie itself.
It's a good movie but it's been nominated for it's undeniable importance, not because it's a great movie.
It is what it is. When the Oscars choose to ignore such cultural zeitgeist event movies, they get called pretentious. This time they chose not to ignore it.
It's not going to win anyway...
