I think the movie is OK at showing how desperate the situation gets, when parents and the police just search and search and search... and search... and search some more, and still cannot find any useful clues to the wereabouts of the missing kids. It gives the sense of hopelessness, of being lost and not knowing what to do. Shows how frustrated people can get. I don't want to spoil it too much, my rating says it clearly... it's an OK movie.
