“Deadbolt” (** out of four) was a thuddingly predictable suspense thriller about a young woman (Rebecca Liddiard) who starts to lose her sanity as she meets a new guy (Jamie Spilchuk) and encounters a series of unexplained disappearances and chilling nocturnal echoes in her home that keep her up at night and keep her nerves on edge. Relatively well-made and with a solid lead performance from Liddiard but film lacks suspense and narrative momentum. Film reunites Liddiard and Spilchuk who were previously in the similarly mediocre “Danger In The House”.
