“Assimilate” (** out of four) was a mediocre teen horror drama about three high-school friends (Joel Courtney, Andi Matachak, and Calum Worthy) who begin making a web series about their town but then uncover some dark secrets when they discover that their neighbors and other townsfolk are being killed and are being killed and replaced by creatures who are perfect copies of their victims. Reasonably well-directed and well-acted but is still a high-school version of “Invasion Of The Body Snatchers” and “The Stepford Wives”. For a movie about copying and cloning, it seems to copy an awful lot from those other two movies.
