“The Darkest Minds” (** out of four) was a wearily derivative futuristic teen melodrama set in yet another dystopian future in which teens are imprisoned by an adult world who fears everyone under the age of 18 and one particular group of teens (Amandla Stenberg, Harris Dickonson, Skylan Brooks, and others) who form a resistance group to fight back and reclaim control of the future and save civilization. By now though, after “The Maze Runner”, “The Hunger Games”, and the “Divergent” series and many others, this may be one futuristic teen sci/fi movie too many. Holds your attention for the first half but never quite gells or takes off. Mandy Moore has a small but key role as Stenberg’s doctor.
