“Witches Of Blackwood” (** out of four) was a curiously flat and glum supernatural thriller about a cop (Cassandra Macgrath) with PTSD who returns home to sort out various family problems and becomes entangled with a group of witches who are plotting out evil doings on her town. Intelligently written and made especially for this type of film and Macgrath does her best to hold this together but it’s a lumpy brew at best. Re-watch “The Craft” or “Witches Of Eastwick” instead.
