“Mercy” (** out of four) was a fair “Die Hard”/”Bourne Identity”/”Taken” knockoff about the Irish mafia (led by Jonathan Rhys-Meyers and Jon Voight) who seize control of a hospital but don’t count on a former military woman (Leah Gibson) who works there as a doctor attempting to thwart them in a skilled battle to the death. If you ever wanted to see Voight with a strained Irish accent, now’s your chance but otherwise there’s not much else here for originality; Rhys-Meyers can play this role in his sleep by now. Hardly the worst of its genre but overall uninspired.
