It's pretty routine until the end that saves it
The center of the movie is the 1917 Houston Riot that involved the 24th Infantry Regiment made up of African Americans. After a series of run ins with the racist police along with attacks on the black community the unit rose up. The main character is played by Trai Byers who went to the Sorbonne in France and signed up for the army to try to improve his people. The story takes a familiar path. It introduces the main characters, has a love affair, has the racist encounters, etc. That makes most of the movie rather routine. The riot and its aftermath are by far the best parts of the film including a dialogue between Byers and Mykelti Williamson who plays a sergeant and a moving image at the very end.
