Jane Campion. Ok, but has she even made a movie since The Piano?
Sofia Coppola. Same question, but with Lost in Translation
Ava DuVernay - I probably should have remembered her
Greta Gerwig - Ok, she's made one fucking movie.
Catherine Hardwicke - Seems she got blackballed a bit after Twilight. Still working, but definitely pushed aside.
Nancy Meyers - She's made a bunch of movies I've heard of, but I've never heard of her. #Patriarchy
I would have to go back and look at what they were up against, but I think Avengers, Guardians, Watchmen, and of course CvS could have all been nominated without anyone but folks like you griping about it. Christ there are up to 10 slots available and they don’t even fill them all most years.
None this year...though I thought if any should, it would be Infinity War. Not only was it excellent, but it does represent the culmination of a truly historic cinematic feat....though the next movie may be more appropriate for that, providing it's good.
Before this? The only one I can think of is Logan.
