What were they thinking? No, honestly, what WERE THEY thinking? John McClane in Russia? Running around Chernobyl to stop a scientist from unleashing his secret stockpile of nuclear grade Uranium on a world flush with rogue terrorist bomb makers? (Oops - sorry…spoiler alert?). Before, our befuddled cop often transplanted to places outside his flatfoot comfort zone, has taken on bad guys in a building, drug thugs in an airport, a bomb-happy heckler from his past, and a computer whiz wanting to destroy the world’s information grid. So nukes aren’t such a bad idea…or are they? Indeed, as the latest installment in the Die Hard series (given the precursory clip “A Good Day to...”) eats up an unhealthy portion of the President’s Day weekend box office, one has to wonder if this was the best approach to keeping a once healthy franchise flourishing.
