“Grimcutty” (** out of four) was an overly grim horror thriller about a teenage girl (Sarah Wolfkind) and her younger brother (Callan Farris) who try to survive when they find that the title internet meme comes to life and threatens to overtake them and destroy their safety and sanity. Initially tense and has some intriguing elements but eventually decays into sheer corn and loses its grip. Wolfkind is solid in the lead; director John Ross shows some promise in his first feature-length film after directing shorts and t.v. series.
