Suspect thriller fails to engage

In Suspect Zero (Sony) a series of unexplained murders (all the victims are themselves killers) puzzle FBI agent Thomas Mackleway (Aaron Eckhart) and appear to be linked to renegade former agent Benjamin O’Ryan (Ben Kingsley).

On the surface this appears to be a good enough basis for a half-decent thriller, but long before the conclusion the wooden script had left me disengaged.
