They made a two hour movie about MLK. Maybe if it were 3 hours like Spike's Malcolm X they could have fit in every person, every detail. But for sake of time they used a representative of SNCC to point out differences, conflict, etc. They use Annie and Amelia to show their presence, their impact. But mostly the movie showed King, it's subject. It didn't try to wipe out the radical element. It talked about how that element was viewed by white people, how King viewed it, how they viewed King. But for sake of time they couldn't give you everyone. It was a movie about MLK. I think Ava Duvernay did a good job.
