“Painkiller” (** out of four) was a muddled thriller melodrama about a middle-aged father (Bill Oberst, Jr) who loses a child to an opioid overdose and goes on a one-man campaign and vigilante quest to go after a corrupt doctor (Michael Pare) and various politicians and pharmaceutical agents who flood the market with opioids. Give director/co-writer Mark Savage points for trying to make a thought-provoking story about the opioid epidemic and the various machinations that profit from it but his points are blunted by scattershot script and unfocused story. Both Oberst and the always-reliable Pare do what they can to keep film on track.
