This is the third installment in the Department Q series. Saw this few days back on a DVD. It begins with a message in a bottle from disappeared children. The movie starts as a kidnapping drama n then turns into a serial killer thriller n later explores the importance of faith. Some may compare this to Prisoners, True Detectives S1 n Marshland. Nonetheless it is a very solid crime thriller. There is sufficient tension n good amount of atmosphere. The cinematography was gorgeous. This time the movie has some decent action sequences too. Trains, helicopters, car chase. Our two leading detectives, Nikolaj Lie Kaas n Fares Fares acted good. The guy who played the serial killer acted well. He is the creepiest and most effective villain of the Department Q films.
