“Detroit” (*** out of four) was a searing recreation of the 1967 Detroit riots in which the National Guard and police had their hands full with a city under siege and how this led to three innocent African-Americans to be murdered and a police force in shambles. Director Kathryn Bigelow once again masterfully recreates time and place and grabs your collar with many raw, powerful moments although story lacks a dramatic center and becomes shapeless after a while. John Boyega and Anthony Mackie stand out in uniformly strong cast. Not the great film it could have been but timely and engrossing.
