Genre
Action
How can we put this clearly? Die Hard is probably the most important action movie of the late 20th-century. We're not exaggerating either. Its influence on the genre is visible everywhere, it's the first movie in a franchise that spans 25 years (and counting), and it singlehandedly redefined and rejuvenated the genre.
We guess you could say there's some romance in there—and perhaps even some comedy—but Die Hard is interested in one thing and one thing only: thrilling its audience with the kick butt antics of its central action hero.
