There’s certainly something very familiar about “To Catch a Killer,” which is a procedural cop thriller about the hunt for an armed and dangerous lunatic who’s developing an interest in committing mass murder. It’s the stuff of film history and, more recently, television, with dozens of shows all chasing the same formula for weekly consumption, playing it safe as viewers begin to treat human misery and sleuthing as comfy sweater entertainment. What’s different about “To Catch a Killer” is its rawness and timing, with co-writer/director Damian Szifron (helming his first picture after 2014’s “Wild Tales”) digging into our modern world of mental illness and armament, emerging with a compelling study of psychological fracture on both sides of the law. There’s striking violence in the movie which is meant to snap viewers to attention, but Szifron brings a balance of realism to the hunt, blended with theatrical police activity, giving the endeavor an unusual atmosphere that should keep its audience invested to the end.
