“The Harrowing” (** out of four) was a sputtering thriller about a series of ritualistic killings which prompt a veteran cop (Matthew Tompkins) to go undercover as a patient in a local forensic hospital under the complete domination of a vindictive doctor (Arnold Vosloo) and soon finds he is losing his mind. Is he actually crazy or are these a side effect of the drugs he has been given? Reasonably well-made and features a few scares along the way but story is more-than-a-little similar to Martin Scorcese’s “Shutter Island” and like that film- it gets more cerebral and lurid (and unpleasant) as it goes along. Michael Ironside has a minor role as Tompkins’ captain but it’s really harrowing at this point what has become of his career.
