Cracked on why Die Hard is the best Christmas movie ever made. And they do make very good points.
The original is a classic with good reason. Still the best action film ever made in my opinion.
Are there movies with better stunts and more spectacular action sequences? Yes. But what Die Hard does that most others don't is that it makes you feel connected to the characters. McClane is just a regular guy. Sure, he's a cop, but he doesn't want to be there. He didn't choose to get involved in the situation, he was just dealt a shitty hand is doing what he can to get out of it. You genuinely feel bad for the guy the whole time and want to see him succeed.
The movie also has one of the great villains in Hans Gruber. Slimy bad guy with a nice flair for style, but also isn't afraid to get his hands dirty. He isn't over the top, and also has fantastic chemistry with McClane.
Another thing that was so refreshing about Die Hard when it first hit was it was one of the first action films where the hero got fucked up real bad. He's beaten, shot, blown up, and cut up before the thing is over. The man is a walking disaster by the end, but he doesnt give up, even if he is just limping along and tired. I love my 80s invincible action heroes as much as the next guy, but it was refreshing to see one that was actually human.
On a different note, I have been thinking lately we need a remake of Die Hard. Keep Alan Rickman as Hans, but now it's Maggie Smith in the McClane role. This little old English lady killing terrorists and giving quippy one liners. It would be awesome.
