This review may contain spoilers. I can handle the truth.
After reading some reviews I realize it is too lenient on the racism and homophobia that are done by some of the characters. At first time watching, I feel it shows the good and the bad of people quite good though, and how dynamic, dramatic, yet mundane life can be (I wrote mundane because in the end there is no big investigation on Angela and Mildred didn't kill her ex husband).
Praises go to the cast, although looking back a little bit, I feel people also overhype or overrate Frances McDormand. I still like Margot Robbie's performance better than McDormand even without deep analysis.
