Matt Millr’s review published on Letterboxd:
The emotion is as brutal as the action. I can't nor never will be able to understand the pain felt by these characters, but Lee does a very good job putting those emotions to film. There are definitely moments where the film steps outside of itself to preach (in my opinion) a little too hard, where I felt the performances were strong enough to deliver the message without that.
I also really can't think of a solid reason for the flashbacks since they don't offer very much narrative or emotional weight that couldn't be handled in the modern day story, but then they wouldn't have had Chadwick Boseman and I do really like his performance in this.
In the end, a very engaging and emotional film that doesn't seem confident enough that it's own narrative can completely drive home the point without some outside help.
