Not a fun movie. In the first part you feel you are in the middle of Detroit’s 1967 race riot. In the next, you are held captive in the Algiers Hotel Annex as a trio of white policemen brutalize a random group of blacks, and two white girls. Then, in almost a coda, you see justice denied, thanks to all-too-familiar legal tactics. Will Poulter, the white police villain, will never get an award for his ugly, but extraordinary portrayal. Director Kathryn Bigelow maybe won’t, but should. Fifty years later we still have Charlottesville and Black Lives Matter, but I like to think Detroit is a historic relic and a useful reminder.
