Happy birthday, Dr. King.
I’m not all that great at movie reviews so won’t pain you with that. Most of what I thought about the movie itself can be found between the lines of this post over on MMM.
In terms of an actual review of the themes of the movie and how well it explores certain topics, I can’t recommend Peter T. Chattaway’s review highly enough. Peter looks at it from a great perspective (no surprise there) and is exponentially better than most of the write-ups I’ve seen.
