DIE HARD (1988)

while all the die hard films are greatly enjoyable films with nothing to take away (the definition of a popcorn film) this is without doubt the most enjoyable one - in fact it was one of the most enjoyable popcorn movies i ever saw with that one line that resonated in my head many days after i originally saw it: Yippee-Ki-Yay
A must for any action movie fan (though i question your action-movie-faness if you are yet to see this film)
