The answer to your first question is yes. Netflix movies to be nominated for a Oscar are as followed:
1) winter on fire
2) The Square
3) What happened miss Simone ( Nina Simone)
Now about your statement about fighting for something else that matters, you act like these people are limited to just fighting for Oscars only? These same black actors also advocate for other causes.
Examples
1) Idris Elba: getting more black politicians involved in America and Britain
2) Will and Jada smith: More investment in education.
You act like these black actors can't walk and chew gum at the same time.
So what is the issue....the academy likes certain movies?
Who fukking cares...why pull out race on this trivial ass issue?
Every African I heard talk about that NFL movie said Will Smith was laughable in that shyt.
Like I said...who cares if white folks like your movie...what is the issue? White folks supposed to be mad because I dont like every Woody Allen movie?
There is a latin grammys...make our own shyt.
As far as other issues...what issue have you seen this many well known black folks come together for?
