Ben Witherington has a nice review of the film here. A key paragraph from his review:
I read Just Mercy almost two years ago and it has added to my education on racial justice. The movie is out and I have not seen it yet, but will write more when I have seen it.
When I say the word “justice” I found in the past that move evangelicals hearing it would by default put the word “social” in front of it. Justice does indeed have a social aspect.
