Ma Rainey’s Black Bottom – 5

Not fun. Viola Davis and Chadwick Boseman play characters that are so unremittingly unpleasant you almost don’t want them onscreen, and the usually reliable Jeremy Shamos is just as bad–that is, sickly fawning–in the other direction. The movie comes across as a play: e.g., stop the action while a character tells his life story. The final five minutes shock the movie to life, but by then it is too late and the dramatic points feel unearned.
