This movie was bittersweet, although it was interesting to see the events of the Boston Marathon bombings re-made on screen, it reminded of the victims of this terrible tragedy. Mark Wahlburg is the head police agent for the Boston police and he helps other agencies involved locate and take down the perpetrators of the bombings. The movie shows the men creating the bombs in their small apartment, and how the police identified them through surveillance tapes on the street. Their attitude about the bombings was surreal, they did not have any remorse and planned a second bombing in New York City. The first perpetrator is caught in a shootout on the street, but the second flees. He is found later hiding in a boat in a neighborhood. The loss of so many lives because of terrorist actions during this event is so saddening. Great movie to see on a rainy day.
