“Glass” (** out of four) was a tiresome sequel to both “Unbreakable” and “Split” about security guard David Dunn (Bruce Willis) who uses his supernatural abilities to capture the multiple-personality serial killer Kevin Crumb (James Macavoy) and they all wind up in a mental hospital with Mr. Glass (Samuel L. Jackson) under the care of a psychiatrist (Sarah Paulson) who tries to suppress and help them eliminate their supernatural powers. Fans of the previous M. Night Shymalahan movies (I wasn’t) and comic book fanatics might like this better. Strong performances (Macavoy is amazing in his scenes) hold your interest for a while but pretentious dialogue and plot developments make this wearying and it never gets off the ground. The director has a minor role as a hospital security guard.
