Yippee-ki-yay, motherfuckers, it's Christmas in July!

Die Hard follows New York City police detective John McClane (Willis) who is caught up in a terrorist takeover of a Los Angeles skyscraper while visiting his estranged wife.

One of the reasons this movie has endured is because it's so well written. Exposition is handled smoothly (through various natural conversations), minor characters are personalized briefly and efficiently, and the suspense just doesn't let up.

Another reason is Alan Rickman.
