It is “Deja Vu” because, yes, you have already seen Denzel Washington in the action thriller hero role before. Many times.

But here, yet again playing a law enforcer getting to the bottom of a tricky case — this time as a federal Alcohol, Tobacco, Firearms and Explosives agent investigating a deadly domestic terrorist bombing and mass murder on a New Orleans ferry boat — the Oscar winner hasn’t lost any of his ability to raise the level of whatever project he chooses. As one of the few leading men around who can consistently wield both serious acting chops and movie star charisma, Washington provides the credibility and watchability to raise what would barely be a serviceable genre piece without him.
