Just watched this inexplicably for the first time, after having seen and adoring its first two sequels. As a teenager when this hit theatres, I never really felt the urge or inclination to see this at the time. Action films weren't big for me back then. Now as a father of a teenager myself, it's interesting seeing what's now considered 'a classic' for the first time.
This easily deserves its lofty status as one of the finest action movies ever made, especially of the 80's. Alan Rickman, now deceased, played with distinction one of the finest cinematic villains ever. This film--closely followed by 'Pulp Fiction'--is the most important work Bruce Willis ever made.
I enthusiastically hope that should someday Willis either leave this plain or decide not to make any more DH films that they simply put the franchise to rest. He was born to play this character. Anyone else in his shoes could never fit the iconic bill.
