The true story of an undercover African American police officer in Ku Klux Klan is stranger than fiction. The premise of this story is fascinating, and the boldness of that officer defies expectations and beliefs. The movie's message is that KKK is a racist organization, and race prejudices of the past are still with us today. These, sadly, are facts that are widely known already...
I also found some of the matters were handled heavy handedly. Again, we know that those issues from 60's and 70's are still persisting. Putting today's political slogans (e.g., build a wall, and make America great again) in the mouth of David Duke - the leader of KKK - is a little too on the nose. Okay, we get what Spike Lee (the director) was trying to say. But the overemphasis on these parallels felt like Spike Lee was trying to force feed his message.
I personally subscribe to liberal views, however, I raise this issue because I prefer nuance in story telling. For example, George Orwell's Animal Farm was a social commentary on its contemporary socio-political situation and Marxism in particular; however, the allegories were used delicately and hence, made a stronger impact.
Props to acting and soundtrack, however, the movie neither entertained nor informed. I'd give it a 4/10.
