A Good Day to Die Hard makes John McClane invincible. That's why his franchise needs the axe.
"Schieß dem Fenster," says Hans Gruber to his subordinate, Karl, as they try to catch the "monkey in the wrench" to their heist plan in 1988's action masterpiece Die Hard. Gruber is trying to tell Karl to shoot the glass, a fact that the audience discovers when Hans repeats himself—in English, oddly, given that they're both native German speakers—in response to Karl's quizzical look. (Viewers have noted over the years that the German words Alan Rickman utters here make no grammatical sense, which could explain Karl's confusion.)
Hans knows that our hero, New York cop John McClane, is out there barefoot, and a floor covered in glass should sideline him at least temporarily. He's right. As they create the shower of shards for McClane to run through to make his escape, they also set up the scene that demonstrates exactly what made Die Hard such a foundation-shaker for action cinema, setting it apart from the films that came before. Sadly, the same elements have set it apart from most of the sequels that have come after.
After that sequence, we next see McClane at the end of an alarmingly thick trail of blood, picking pieces of glass out of his foot. But he's not doing it with steely resolve, gritting his teeth and planning his revenge. He's in clearly debilitating pain. Choking back tears on the radio to his pal Sgt. Powell on the outside, he basically says he's probably not getting out of the Nakatomi building alive.
We latched onto Die Hard's version of John McClane because he's a relatable hero, an everyman with a quick wit and real vulnerability. Up to that point, audiences knew Willis primarily as the sarcastic, flirty private eye on TV's Moonlighting, and from lead roles in a couple of Blake Edwards comedies. At that time, Willis as an action hero was as out of left field as if Paul Rudd had been cast as Jason Bourne—and it's even weirder when you consider that Die Hard came out in an era when Stallone, Schwarzenegger, and Van Damme were the template for the successful action star.
Die Hard works so brilliantly because even if we know that action-movie rules dictate that McClane is going to win, we can't get it out of our head that this guy really could die. The words chosen for the title aren't insignificant in this respect: Die Hard means something very different from, say, Die Impossible, and the latter is closer to the spirit of the standard-issue '80s action flick—and to what the Die Hard series has become.
Director John Moore was keen to include plenty of references to the original Die Hard in his latest chapter, A Good Day to Die Hard, out this week. While his visual quotation of Gruber falling to his death in one scene was amusing, there's another parallel scene that underlines just how Die Hard really has become Die Impossible.
In the original film, McClane manages to escape from attack on a rooftop by tying a fire hose around his waist and leaping off the side of the building. He then has to do some glass-shooting of his own, breaking a window to get back in. People fall easily through windows all the time in movies, so his need for extra firepower to get through was a refreshingly realistic touch.
In A Good Day to Die Hard, McClane goes through an exterior window in much the same fashion. Moore films the moment in the gratuitous, Zach Snyder-like slow motion that he favors in (too) many of the movie's key moments, and the slowed-down speed actually highlights the implausibility of the sequence. We now have an agonizingly long period of time to ponder how he smashes so easily not just through an exterior window but also the presumably even-more-sturdy frame of the window at the center of his impact point. Apparently John McClane is now part wrecking ball.
The implausibility of McClane actually still being alive doesn't even have anything to do with his growing older; it's just a matter of the stunts getting more and more outlandish.
Most action movies require a healthy suspension of disbelief. That isn't a problem, so long as the film earns it. Could someone actually jump off a roof with a fire hose wrapped around their waist and survive the jolt at the bottom? That's probably a question for the Mythbusters, but as presented in the movie, I was willing to buy it. The gore of the glass-walking aftermath, and the affecting defeatism of Willis's performance earlier, help sell these later strains in plausibility.
