“The Vindicator” (*1/2 out of four) was a vindictively awful pulp horror melodrama dud about a live-streaming podcast on true crime whose host (Chris Maher) and show are invaded by a real-life serial killer (Sean Berube) who challenges and perpetuates the host and a few contestants to nightmarish tasks that lead them all to a deadly battle over who will survive. What initially seems like a lame attempt to parody the irony of reality television and horror turns into a slavish imitation of “Saw” and becomes a heavy-handed mess. Martin Scorcese’s “The King Of Comedy” went over similar elements far more darkly (and entertainingly) over 40 years ago!
