“Nefarious” (* out of four) was a grating horror thriller about a convicted serial killer (Sean Patrick Flannery) who gets a psychiatric evaluation from a prison worker (Jordan Belfi) and claims to be (yawn) the spirit of the title demon who will curse the prison worker to commit a series of three murders on his own. The talented Flannery backfires horribly in the lead role in an unbearable performance that is irritating and over-the-top; the rest of the proceedings are static and stupid. Obviously inspired by “The Silence Of The Lambs” and “Manhunter” but fans of those films would be better off having some fava beans and a nice chianti instead of this mess.
