“Cassidy Way” (** out of four) was a tepid horror thriller about a vengeful father (Christopher Rich) distraught over the death of his son who enacts his revenge over a documentary film crew who he thinks may have been responsible inadvertently for his son’s death. Rich’s strong performance is the highlight of this violent revenge thriller which ventures off into “Saw” territory as he kidnaps and tortures his victims. If that’s your cup of tea, it’s all yours, but it’s a difficult brew for others.
